data Returning a b where Source #

Don't use this internal datatype. Instead you probably want rCount or rReturning.

Arguments

:: Default FromFields columnsReturned haskells 
=> Connection 
-> Table a columnsR

Table to delete rows from

-> (columnsR -> Column SqlBool)

Predicate function f to choose which rows to delete. runDeleteReturning will delete rows for which f returns TRUE and leave unchanged rows for which f returns FALSE.

-> (columnsR -> columnsReturned) 
-> IO [haskells]

Returned rows which have been deleted
