    • countRowsInTable

      public static int countRowsInTable(JdbcTemplate jdbcTemplate, 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, String tableName, 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, 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, String tableName, String whereClause, 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, String... tableNames)
      Drop the specified tables.
      Parameters:
      jdbcTemplate - the JdbcTemplate with which to perform JDBC operations
      tableNames - the names of the tables to drop
