Method Detail

unparseDateTimeLiteral

public void unparseDateTimeLiteral(SqlWriter writer,
                                   SqlAbstractDateTimeLiteral literal,
                                   int leftPrec,
                                   int rightPrec)

Overrides:

unparseDateTimeLiteral in class SqlDialect

unparseCall

public void unparseCall(SqlWriter writer,
                        SqlCall call,
                        int leftPrec,
                        int rightPrec)

Overrides:

unparseCall in class SqlDialect

unparseFloor

private void unparseFloor(SqlWriter writer,
                          SqlCall call)

Unparses datetime floor for Microsoft SQL Server. There is no TRUNC function, so simulate this using calls to CONVERT.

Parameters:

writer - Writer

call - Call

unparseFloorWithUnit

private void unparseFloorWithUnit(SqlWriter writer,
                                  SqlCall call,
                                  int charLen,
                                  String offset)
