方法详细资料

countRowsInTable

public static int countRowsInTable(cn.taketoday.jdbc.core.JdbcOperations jdbcTemplate,
 String tableName)

Count the rows in the given table.

参数:

jdbcTemplate - the JdbcOperations with which to perform JDBC operations

tableName - name of the table to count rows in

返回:

the number of rows in the table

countRowsInTable

public static int countRowsInTable(cn.taketoday.jdbc.core.simple.JdbcClient jdbcClient,
 String tableName)

Count the rows in the given table.

参数:

jdbcClient - the JdbcClient with which to perform JDBC operations

tableName - name of the table to count rows in

返回:

the number of rows in the table

countRowsInTableWhere

public static int countRowsInTableWhere(cn.taketoday.jdbc.core.JdbcOperations jdbcTemplate,
 String tableName,
 @Nullable
 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".

参数:

jdbcTemplate - the JdbcOperations 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

返回:

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

countRowsInTableWhere

public static int countRowsInTableWhere(cn.taketoday.jdbc.core.simple.JdbcClient jdbcClient,
 String tableName,
 @Nullable
 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".

参数:

jdbcClient - the JdbcClient 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

返回:

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

deleteFromTables

public static int deleteFromTables(cn.taketoday.jdbc.core.JdbcOperations jdbcTemplate,
 String... tableNames)

Delete all rows from the specified tables.

参数:

jdbcTemplate - the JdbcOperations with which to perform JDBC operations

tableNames - the names of the tables to delete from

返回:

the total number of rows deleted from all specified tables

deleteFromTables

public static int deleteFromTables(cn.taketoday.jdbc.core.simple.JdbcClient jdbcClient,
 String... tableNames)

Delete all rows from the specified tables.

参数:

jdbcClient - the JdbcClient with which to perform JDBC operations

tableNames - the names of the tables to delete from

返回:

the total number of rows deleted from all specified tables

deleteFromTableWhere

public static int deleteFromTableWhere(cn.taketoday.jdbc.core.JdbcOperations 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.

参数:

jdbcTemplate - the JdbcOperations 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.

返回:

the number of rows deleted from the table

deleteFromTableWhere

public static int deleteFromTableWhere(cn.taketoday.jdbc.core.simple.JdbcClient jdbcClient,
 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.

参数:

jdbcClient - the JdbcClient 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.

返回:

the number of rows deleted from the table

dropTables

public static void dropTables(cn.taketoday.jdbc.core.JdbcOperations jdbcTemplate,
 String... tableNames)

Drop the specified tables.

参数:

jdbcTemplate - the JdbcOperations with which to perform JDBC operations

tableNames - the names of the tables to drop

dropTables

public static void dropTables(cn.taketoday.jdbc.core.simple.JdbcClient jdbcClient,
 String... tableNames)

Drop the specified tables.

参数:

jdbcClient - the JdbcClient with which to perform JDBC operations

tableNames - the names of the tables to drop
