QueryRunner

public QueryRunner()

Constructor for QueryRunner.

QueryRunner

public QueryRunner(boolean pmdKnownBroken)

Constructor for QueryRunner that controls the use of ParameterMetaData.

参数:

pmdKnownBroken - Some drivers don't support ParameterMetaData.getParameterType(int); if pmdKnownBroken is set to true, we won't even try it; if false, we'll try it, and if it breaks, we'll remember not to use it again.

QueryRunner

public QueryRunner(DataSource ds)

Constructor for QueryRunner that takes a DataSource to use. Methods that do not take a Connection parameter will retrieve connections from this DataSource.

参数:

ds - The DataSource to retrieve connections from.

QueryRunner

public QueryRunner(DataSource ds,
                   boolean pmdKnownBroken)

Constructor for QueryRunner that takes a DataSource and controls the use of ParameterMetaData. Methods that do not take a Connection parameter will retrieve connections from this DataSource.

参数:

ds - The DataSource to retrieve connections from.

pmdKnownBroken - Some drivers don't support ParameterMetaData.getParameterType(int); if pmdKnownBroken is set to true, we won't even try it; if false, we'll try it, and if it breaks, we'll remember not to use it again.
