All Implemented Interfaces:

SimpleJdbcCallOperations

public class SimpleJdbcCall
extends AbstractJdbcCall
implements SimpleJdbcCallOperations

A SimpleJdbcCall is a multi-threaded, reusable object representing a call to a stored procedure or a stored function. It provides meta data processing to simplify the code needed to access basic stored procedures/functions. All you need to provide is the name of the procedure/function and a Map containing the parameters when you execute the call. The names of the supplied parameters will be matched up with in and out parameters declared when the stored procedure was created.

The meta data processing is based on the DatabaseMetaData provided by the JDBC driver. Since we rely on the JDBC driver this "auto-detection" can only be used for databases that are known to provide accurate meta data. These currently include Derby, MySQL, Microsoft SQL Server, Oracle, DB2, Sybase and PostgreSQL. For any other databases you are required to declare all parameters explicitly. You can of course declare all parameters explicitly even if the database provides the necessary meta data. In that case your declared parameters will take precedence. You can also turn off any mete data processing if you want to use parameter names that do not match what is declared during the stored procedure compilation.

The actual insert is being handled using Spring's JdbcTemplate.

Many of the configuration methods return the current instance of the SimpleJdbcCall to provide the ability to string multiple ones together in a "fluid" interface style.

Constructor Detail

SimpleJdbcCall

public SimpleJdbcCall(javax.sql.DataSource dataSource)

Constructor that takes one parameter with the JDBC DataSource to use when creating the JdbcTemplate.

Parameters:

dataSource - the DataSource to use

See Also:

JdbcAccessor.setDataSource(javax.sql.DataSource)

SimpleJdbcCall

public SimpleJdbcCall(JdbcTemplate jdbcTemplate)

Alternative Constructor that takes one parameter with the JdbcTemplate to be used.

Method Detail

withProcedureName

public SimpleJdbcCall withProcedureName(java.lang.String procedureName)

Description copied from interface: SimpleJdbcCallOperations

Specify the procedure name to be used - this implies that we will be calling a stored procedure.

Specified by:

withProcedureName in interface SimpleJdbcCallOperations

Parameters:

procedureName - the name of the stored procedure

Returns:

the instance of this SimpleJdbcCall

withFunctionName

public SimpleJdbcCall withFunctionName(java.lang.String functionName)

Description copied from interface: SimpleJdbcCallOperations

Specify the procedure name to be used - this implies that we will be calling a stored function.

Specified by:

withFunctionName in interface SimpleJdbcCallOperations

Parameters:

functionName - the name of the stored function

Returns:

the instance of this SimpleJdbcCall

withSchemaName

public SimpleJdbcCall withSchemaName(java.lang.String schemaName)

Optionally, specify the name of the schema that contins the stored procedure.

Specified by:

withSchemaName in interface SimpleJdbcCallOperations

Parameters:

schemaName - the name of the schema

Returns:

the instance of this SimpleJdbcCall

withCatalogName

public SimpleJdbcCall withCatalogName(java.lang.String catalogName)

Description copied from interface: SimpleJdbcCallOperations

Optionally, specify the name of the catalog that contins the stored procedure. To provide consistency with the Oracle DatabaseMetaData, this is used to specify the package name if the procedure is declared as part of a package.

Specified by:

withCatalogName in interface SimpleJdbcCallOperations

declareParameters

public SimpleJdbcCall declareParameters(SqlParameter... sqlParameters)

Description copied from interface: SimpleJdbcCallOperations

Specify one or more parameters if desired. These parameters will be supplemented with any parameter information retrieved from the database meta data. Note that only parameters declared as SqlParameter and SqlInOutParameter will be used to provide input values. This is different from the StoredProcedure class which for backwards compatibility reasons allows input values to be provided for parameters declared as SqlOutParameter.

Specified by:

                                RowMapper rowMapper)

Description copied from interface: SimpleJdbcCallOperations

Used to specify when a ResultSet is returned by the stored procedure and you want it mapped by a RowMapper. The results will be returned using the parameter name specified. Multiple ResultSets must be declared in the correct order. If the database you are using uses ref cursors then the name specified must match the name of the parameter declared for the procedure in the database.

Specified by:

returningResultSet in interface SimpleJdbcCallOperations
