Methods

as(String alias) → MssqlAliased

Available on MssqlExpression, provided by the MssqlExpressionOperators extension

Gives this expression a result alias.

Available on MssqlExpression, provided by the MssqlExpressionOperators extension

betweenColumns(String lower, String upper) → MssqlCondition

Available on MssqlExpression, provided by the MssqlExpressionOperators extension

BETWEEN two other columns rather than two values.
