What the column is in SQL, or null for a hand-written column that never said.

final, inherited

hashCode → int

The hash code for this object.

no setter, inherited

isNullable → bool

Whether SQL says this column can be null.

no setter, inherited

name → String

The column's own name, without any qualifier.

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

source → MssqlSourceRef?

The source this column belongs to, or null when it was written in full.

Methods

as(String alias) → MssqlAliased

Available on MssqlExpression, provided by the MssqlExpressionOperators extension

Gives this expression a result alias.

asc({MssqlNulls? nulls}) → MssqlOrder

Available on MssqlExpression, provided by the MssqlExpressionOperators extension

Orders by this expression, ascending.

at(MssqlSourceRef source) → MssqlTypedColumn<double>

This column, seen through another source.

inherited

between(double lower, double upper) → MssqlCondition

inherited

between(Object? lower, Object? upper) → MssqlCondition

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.

compile(MssqlParameterAllocator parameters, MssqlDialect dialect) → String

Writes this expression's SQL, binding any values through parameters.

inherited

desc({MssqlNulls? nulls}) → MssqlOrder

Available on MssqlExpression, provided by the MssqlExpressionOperators extension

Orders by this expression, descending.

eq(double value) → MssqlCondition

Typed comparisons. The untyped versions on MssqlExpression stay available for untyped columns; these shadow them with a narrower operand.

inherited

eq(Object? value) → MssqlCondition

Available on MssqlExpression, provided by the MssqlExpressionOperators extension

eqCol(String identifier) → MssqlCondition

Available on MssqlExpression, provided by the MssqlExpressionOperators extension

Compares this expression to another column rather than to a value.

eqExpr(MssqlExpression other) → MssqlCondition

Available on MssqlExpression, provided by the MssqlExpressionOperators extension

Compares this expression to another expression.
