方法详细资料

buildJdbcFieldType

public static FieldType buildJdbcFieldType(int type)

fillPreparedStatementParameters

public static void fillPreparedStatementParameters(List<Object> parameters,
                                                   PreparedStatement stmt)
                                            throws Exception

抛出:

Exception

rollback

public static void rollback(Connection conn)

setAutoCommit

public static void setAutoCommit(Connection conn,
                                 boolean autoCommit)

closeConnection

public static void closeConnection(Connection con)

Close the given JDBC Connection and ignore any thrown exception. This is useful for typical finally blocks in manual JDBC code.

参数:

con - the JDBC Connection to close (may be null)

rollbackConnection

public static void rollbackConnection(Connection con)

closeStatement

public static void closeStatement(Statement stmt)

Close the given JDBC Statement and ignore any thrown exception. This is useful for typical finally blocks in manual JDBC code.

参数:

stmt - the JDBC Statement to close (may be null)

closeResultSet

public static void closeResultSet(ResultSet rs)

Close the given JDBC ResultSet and ignore any thrown exception. This is useful for typical finally blocks in manual JDBC code.

参数:

rs - the JDBC ResultSet to close (may be null)

checkTableExists

public static boolean checkTableExists(Connection conn,
                                       String tableName)
