JdbcTemplate (Spring Framework 5.2.8.RELEASE API)

java.lang.Object
- org.springframework.jdbc.support.JdbcAccessor
- - org.springframework.jdbc.core.JdbcTemplate

All Implemented Interfaces:

InitializingBean, JdbcOperations
```
public class JdbcTemplate
extends JdbcAccessor
implements JdbcOperations
```
This is the central class in the JDBC core package. It simplifies the use of JDBC and helps to avoid common errors. It executes core JDBC workflow, leaving application code to provide SQL and extract results. This class executes SQL queries or updates, initiating iteration over ResultSets and catching JDBC exceptions and translating them to the generic, more informative exception hierarchy defined in the org.springframework.dao package.
Code using this class need only implement callback interfaces, giving them a clearly defined contract. The PreparedStatementCreator callback interface creates a prepared statement given a Connection, providing SQL and any necessary parameters. The ResultSetExtractor interface extracts values from a ResultSet. See also PreparedStatementSetter and RowMapper for two popular alternative callback interfaces.
Can be used within a service implementation via direct instantiation with a DataSource reference, or get prepared in an application context and given to services as bean reference. Note: The DataSource should always be configured as a bean in the application context, in the first case given to the service directly, in the second case to the prepared template.
Because this class is parameterizable by the callback interfaces and the SQLExceptionTranslator interface, there should be no need to subclass it.
All SQL operations performed by this class are logged at debug level, using "org.springframework.jdbc.core.JdbcTemplate" as log category.
NOTE: An instance of this class is thread-safe once configured.

- Constructor Detail
  - JdbcTemplate
```
public JdbcTemplate()
```
    Construct a new JdbcTemplate for bean usage.
    Note: The DataSource has to be set before using the instance.
    
    See Also:
    
    JdbcAccessor.setDataSource(javax.sql.DataSource)
  - JdbcTemplate
```
public JdbcTemplate(DataSource dataSource)
```
    Construct a new JdbcTemplate, given a DataSource to obtain connections from.
    Note: This will not trigger initialization of the exception translator.
    
    Parameters:
    
    dataSource - the JDBC DataSource to obtain connections from
  - JdbcTemplate
```
public JdbcTemplate(DataSource dataSource,
                    boolean lazyInit)
```
    Construct a new JdbcTemplate, given a DataSource to obtain connections from.
    Note: Depending on the "lazyInit" flag, initialization of the exception translator will be triggered.
    
    Parameters:
    
    dataSource - the JDBC DataSource to obtain connections from
    
    lazyInit - whether to lazily initialize the SQLExceptionTranslator
- Method Detail
  - setIgnoreWarnings
```
public void setIgnoreWarnings(boolean ignoreWarnings)
```
    Set whether or not we want to ignore SQLWarnings.
    Default is "true", swallowing and logging all warnings. Switch this flag to "false" to make the JdbcTemplate throw an SQLWarningException instead.
    
    See Also:
    
    SQLWarning, SQLWarningException, handleWarnings(java.sql.Statement)
  - isIgnoreWarnings
```
public boolean isIgnoreWarnings()
```
    Return whether or not we ignore SQLWarnings.
  - setFetchSize
```
public void setFetchSize(int fetchSize)
```
    Set the fetch size for this JdbcTemplate. This is important for processing large result sets: Setting this higher than the default value will increase processing speed at the cost of memory consumption; setting this lower can avoid transferring row data that will never be read by the application.
    Default is -1, indicating to use the JDBC driver's default configuration (i.e. to not pass a specific fetch size setting on to the driver).
    Note: As of 4.3, negative values other than -1 will get passed on to the driver, since e.g. MySQL supports special behavior for Integer.MIN_VALUE.
    
    See Also:
    
    Statement.setFetchSize(int)
  - getFetchSize
```
public int getFetchSize()
```
    Return the fetch size specified for this JdbcTemplate.
  - setMaxRows
```
public void setMaxRows(int maxRows)
```
    Set the maximum number of rows for this JdbcTemplate. This is important for processing subsets of large result sets, avoiding to read and hold the entire result set in the database or in the JDBC driver if we're never interested in the entire result in the first place (for example, when performing searches that might return a large number of matches).
    Default is -1, indicating to use the JDBC driver's default configuration (i.e. to not pass a specific max rows setting on to the driver).
    Note: As of 4.3, negative values other than -1 will get passed on to the driver, in sync with setFetchSize(int)'s support for special MySQL values.
    
    See Also:
    
    Statement.setMaxRows(int)
  - getMaxRows
```
public int getMaxRows()
```
    Return the maximum number of rows specified for this JdbcTemplate.
  - setQueryTimeout
```
public void setQueryTimeout(int queryTimeout)
```
    Set the query timeout for statements that this JdbcTemplate executes.
    Default is -1, indicating to use the JDBC driver's default (i.e. to not pass a specific query timeout setting on the driver).
    Note: Any timeout specified here will be overridden by the remaining transaction timeout when executing within a transaction that has a timeout specified at the transaction level.
    
    See Also:
    
    Statement.setQueryTimeout(int)
  - getQueryTimeout
```
public int getQueryTimeout()
```
    Return the query timeout for statements that this JdbcTemplate executes.
  - setSkipResultsProcessing
```
public void setSkipResultsProcessing(boolean skipResultsProcessing)
```
    Set whether results processing should be skipped. Can be used to optimize callable statement processing when we know that no results are being passed back - the processing of out parameter will still take place. This can be used to avoid a bug in some older Oracle JDBC drivers like 10.1.0.2.
  - isSkipResultsProcessing
```
public boolean isSkipResultsProcessing()
```
    Return whether results processing should be skipped.
  - setSkipUndeclaredResults
```
public void setSkipUndeclaredResults(boolean skipUndeclaredResults)
```
    Set whether undeclared results should be skipped.
  - isSkipUndeclaredResults
```
public boolean isSkipUndeclaredResults()
```
    Return whether undeclared results should be skipped.
  - setResultsMapCaseInsensitive
```
public void setResultsMapCaseInsensitive(boolean resultsMapCaseInsensitive)
```
    Set whether execution of a CallableStatement will return the results in a Map that uses case insensitive names for the parameters.
  - isResultsMapCaseInsensitive
```
public boolean isResultsMapCaseInsensitive()
```
    Return whether execution of a CallableStatement will return the results in a Map that uses case insensitive names for the parameters.
  - execute
```

    execute in interface JdbcOperations
    
    Parameters:
    
    action - a callback object that specifies the action
    
    Returns:
    
    a result object returned by the action, or null if none
    
    Throws:
    
    DataAccessException - if there is any problem
  - createConnectionProxy
```
protected Connection createConnectionProxy(Connection con)
```
    Create a close-suppressing proxy for the given JDBC Connection. Called by the execute method.
    The proxy also prepares returned JDBC Statements, applying statement settings such as fetch size, max rows, and query timeout.
    
    Parameters:
    
    con - the JDBC Connection to create a proxy for
    
    Returns:

```
    Description copied from interface: JdbcOperations
    
    Execute a query given static SQL, mapping a single result row to a result object via a RowMapper.
    Uses a JDBC Statement, not a PreparedStatement. If you want to execute a static query with a PreparedStatement, use the overloaded JdbcOperations.queryForObject(String, RowMapper, Object...) method with null as argument array.
    
    Specified by:
    
    queryForObject in interface JdbcOperations
    
    Parameters:
    
    sql - the SQL query to execute
    
    rowMapper - a callback that will map one object per row
    
    Returns:
    
    the single mapped object (may be null if the given RowMapper returned null)
    
    Throws:
    
    IncorrectResultSizeDataAccessException - if the query does not return exactly one row
    
    DataAccessException - if there is any problem executing the query

```
    Description copied from interface: JdbcOperations
    
    Execute a query for a result object, given static SQL.
    Uses a JDBC Statement, not a PreparedStatement. If you want to execute a static query with a PreparedStatement, use the overloaded JdbcOperations.queryForObject(String, Class, Object...) method with null as argument array.
    This method is useful for running static SQL with a known outcome. The query is expected to be a single row/single column query; the returned result will be directly mapped to the corresponding object type.
    
    Specified by:
    
    queryForObject in interface JdbcOperations
    
    Parameters:
    
    sql - the SQL query to execute
    
    requiredType - the type that the result object is expected to match
    
    Returns:
    
    the result object of the required type, or null in case of SQL NULL
    
    Throws:
    
    IncorrectResultSizeDataAccessException - if the query does not return exactly one row, or does not return exactly one column in that row
    
    DataAccessException - if there is any problem executing the query

```
    Description copied from interface: JdbcOperations
    
    Execute a query for a result list, given static SQL.
    Uses a JDBC Statement, not a PreparedStatement. If you want to execute a static query with a PreparedStatement, use the overloaded queryForList method with null as argument array.
    The results will be mapped to a List (one entry for each row) of result objects, each of them matching the specified element type.
    
    Specified by:
    
    queryForList in interface JdbcOperations
    
    Parameters:
    
    sql - the SQL query to execute
    
    elementType - the required type of element in the result list (for example, Integer.class)
    
    Returns:
    
    a List of objects that match the specified element type
    
    Throws:

    Description copied from interface: JdbcOperations
    
    Execute a query for a result list, given static SQL.
    Uses a JDBC Statement, not a PreparedStatement. If you want to execute a static query with a PreparedStatement, use the overloaded queryForList method with null as argument array.
    The results will be mapped to a List (one entry for each row) of Maps (one entry for each column using the column name as the key). Each element in the list will be of the form returned by this interface's queryForMap methods.
    
    Specified by:
    
    queryForList in interface JdbcOperations
    
    Parameters:
    
    sql - the SQL query to execute
    
    Returns:
    
    an List that contains a Map per row

```
    Description copied from interface: JdbcOperations
    
    Execute a query for an SqlRowSet, given static SQL.
    Uses a JDBC Statement, not a PreparedStatement. If you want to execute a static query with a PreparedStatement, use the overloaded queryForRowSet method with null as argument array.
    The results will be mapped to an SqlRowSet which holds the data in a disconnected fashion. This wrapper will translate any SQLExceptions thrown.
    Note that, for the default implementation, JDBC RowSet support needs to be available at runtime: by default, Sun's com.sun.rowset.CachedRowSetImpl class is used, which is part of JDK 1.5+ and also available separately as part of Sun's JDBC RowSet Implementations download (rowset.jar).
    
    Specified by:
    
    queryForRowSet in interface JdbcOperations
    
    Parameters:
    
    sql - the SQL query to execute
    
    Returns:
    
    an SqlRowSet representation (possibly a wrapper around a javax.sql.rowset.CachedRowSet)
    
    Throws:
    
    DataAccessException - if there is any problem executing the query

```
    Description copied from interface: JdbcOperations
    
    Execute a JDBC data access operation, implemented as callback action working on a JDBC PreparedStatement. This allows for implementing arbitrary data access operations on a single Statement, within Spring's managed JDBC environment: that is, participating in Spring-managed transactions and converting JDBC SQLExceptions into Spring's DataAccessException hierarchy.
    The callback action can return a result object, for example a domain object or a collection of domain objects.
    
    Specified by:
    
    execute in interface JdbcOperations
    
    Parameters:
    
    psc - a callback that creates a PreparedStatement given a Connection

    The results will be mapped to an SqlRowSet which holds the data in a disconnected fashion. This wrapper will translate any SQLExceptions thrown.
    Note that, for the default implementation, JDBC RowSet support needs to be available at runtime: by default, Sun's com.sun.rowset.CachedRowSetImpl class is used, which is part of JDK 1.5+ and also available separately as part of Sun's JDBC RowSet Implementations download (rowset.jar).
    
    Specified by:
    
    queryForRowSet in interface JdbcOperations
    
    Parameters:
    
    sql - the SQL query to execute
    
    args - arguments to bind to the query (leaving it to the PreparedStatement to guess the corresponding SQL type); may also contain SqlParameterValue objects which indicate not only the argument value but also the SQL type and optionally the scale
    
    Returns:
    
    an SqlRowSet representation (possibly a wrapper around a javax.sql.rowset.CachedRowSet)
    
    Throws:
    
    DataAccessException - if there is any problem executing the query
