getColumnTypeSQL

public String getColumnTypeSQL(Column column)

Specified by:

getColumnTypeSQL in interface Dialect

Overrides:

getColumnTypeSQL in class DefaultDialect

getConcatFunctionSQL

public String getConcatFunctionSQL(Column[] columns)

Specified by:

getConcatFunctionSQL in interface Dialect

Overrides:

getConcatFunctionSQL in class DefaultDialect

getDatePartFunctionSQL

public String getDatePartFunctionSQL(String part,
                                     Column column)

Specified by:

getDatePartFunctionSQL in interface Dialect

Overrides:

getDatePartFunctionSQL in class DefaultDialect

getDateParameterSQL

public String getDateParameterSQL(Date param)

Specified by:

getDateParameterSQL in interface Dialect

Overrides:

getCountQuerySQL

public String getCountQuerySQL(Select select)

Specified by:

getCountQuerySQL in interface Dialect

Overrides:

getCountQuerySQL in class DefaultDialect

getSQL

public String getSQL(Select select)

Since SQL Server 2012 pagination queries are resolved as follows:

• 1. offset <= 0 limit > 0

SELECT TOP limit * FROM "EXPENSE_REPORTS"

• 2. offset > 0 limit > 0

SELECT * FROM "EXPENSE_REPORTS" ORDER BY DEPARTMENT OFFSET offset ROWS FETCH NEXT limit ROWS ONLY

This second case requires a mandatory order by clause.

The methods below implement the above requirements.
