Method Detail

countRowsInTable

public static int countRowsInTable(JdbcTemplate jdbcTemplate,
                                   java.lang.String tableName)

Count the rows in the given table.

Parameters:

jdbcTemplate - the JdbcTemplate with which to perform JDBC operations

tableName - name of the table to count rows in

Returns:

the number of rows in the table

countRowsInTableWhere

public static int countRowsInTableWhere(JdbcTemplate jdbcTemplate,
                                        java.lang.String tableName,
                                        java.lang.String whereClause)

Count the rows in the given table, using the provided WHERE clause.

If the provided WHERE clause contains text, it will be prefixed with " WHERE " and then appended to the generated SELECT statement. For example, if the provided table name is "person" and the provided where clause is "name = 'Bob' and age > 25", the resulting SQL statement to execute will be "SELECT COUNT(0) FROM person WHERE name = 'Bob' and age > 25".

Parameters:

jdbcTemplate - the JdbcTemplate with which to perform JDBC operations

tableName - the name of the table to count rows in

whereClause - the WHERE clause to append to the query

Returns:

the number of rows in the table that match the provided WHERE clause

deleteFromTables

public static int deleteFromTables(JdbcTemplate jdbcTemplate,
                                   java.lang.String... tableNames)

Delete all rows from the specified tables.

Parameters:

jdbcTemplate - the JdbcTemplate with which to perform JDBC operations

tableNames - the names of the tables to delete from

Returns:

the total number of rows deleted from all specified tables

deleteFromTableWhere

public static int deleteFromTableWhere(JdbcTemplate jdbcTemplate,
                                       java.lang.String tableName,
                                       java.lang.String whereClause,
                                       java.lang.Object... args)

Delete rows from the given table, using the provided WHERE clause.

If the provided WHERE clause contains text, it will be prefixed with " WHERE " and then appended to the generated DELETE statement. For example, if the provided table name is "person" and the provided where clause is "name = 'Bob' and age > 25", the resulting SQL statement to execute will be "DELETE FROM person WHERE name = 'Bob' and age > 25".

As an alternative to hard-coded values, the "?" placeholder can be used within the WHERE clause, binding to the given arguments.

Parameters:

jdbcTemplate - the JdbcTemplate with which to perform JDBC operations

tableName - the name of the table to delete rows from

whereClause - the WHERE clause to append to the query

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:

the number of rows deleted from the table

dropTables

public static void dropTables(JdbcTemplate jdbcTemplate,
                              java.lang.String... tableNames)

Drop the specified tables.

Parameters:

jdbcTemplate - the JdbcTemplate with which to perform JDBC operations

tableNames - the names of the tables to drop

Do not use this method to execute DDL if you expect rollback.

Parameters:

jdbcTemplate - the JdbcTemplate with which to perform JDBC operations

resourceLoader - the resource loader with which to load the SQL script

sqlResourcePath - the Spring resource path for the SQL script

continueOnError - whether or not to continue without throwing an exception in the event of an error

Throws:

DataAccessException - if there is an error executing a statement and continueOnError is false

Execute the given SQL script.

The script will typically be loaded from the classpath. Statements should be delimited with a semicolon. If statements are not delimited with a semicolon then there should be one statement per line. Statements are allowed to span lines only if they are delimited with a semicolon. Any line comments will be removed.

Do not use this method to execute DDL if you expect rollback.

Parameters:

jdbcTemplate - the JdbcTemplate with which to perform JDBC operations

resource - the resource to load the SQL script from

continueOnError - whether or not to continue without throwing an exception in the event of an error

Throws:

DataAccessException - if there is an error executing a statement and continueOnError is false

resource - the resource (potentially associated with a specific encoding) to load the SQL script from

continueOnError - whether or not to continue without throwing an exception in the event of an error

Throws:

Deprecated. as of Spring 4.0.3, in favor of using ScriptUtils.splitSqlScript(String, char, List)

Split an SQL script into separate statements delimited by the provided delimiter character. Each individual statement will be added to the provided List.

Within a statement, "--" will be used as the comment prefix; any text beginning with the comment prefix and extending to the end of the line will be omitted from the statement. In addition, multiple adjacent whitespace characters will be collapsed into a single space.

Parameters:

script - the SQL script

delim - character delimiting each statement — typically a ';' character

statements - the list that will contain the individual statements
