getReplacementStatement(Statement statement)

public default Statement getReplacementStatement(Statement statement)

getSql()

public abstract String[] getSql()

Returns the static SQL string associated with this local statement. A statement should include a SQL statement for each variant that can reasonably be expected to be generated by a framework, but does not need to include a variant for each theoretically possible variant. The given SQL strings will be used as the keys in a java.util.Map for quick lookup. This means that it will not match all possible variants of the statement, which is OK, as this is only intended to cover auto-generated query strings from frameworks/tools.

Returns
Type	Description
`String[]`

hasReplacementStatement()

public default boolean hasReplacementStatement()

Returns true if the statement has a static replacement SQL string.

Returns
Type	Description
`boolean`
