Description

MSSQL Types Update

This module defines the Update-related IR types specific to MSSQL.

Synopsis

data UpdateOperator v
- = UpdateSet v
- | UpdateInc v
type UpdateSet = HashMap ColumnName (UpdateOperator Expression)
type UpdateOutput = Output Inserted
data Update = Update {
- updateTable :: Aliased TableName
- updateSet :: UpdateSet
- updateOutput :: UpdateOutput
- updateTempTable :: TempTable
- updateWhere :: Where
}

Documentation

data UpdateOperator v Source #

The various update operators supported by MSSQL, i.e. the _set, _inc operators that appear in the schema.

TODO: Docs for MSSQL! See Update Mutations User docs

Constructors
