parseStatementsWithPosition

Arguments

:: FilePath

filename to use in errors

-> Int

adjust line number in errors by adding this

-> Int

adjust column in errors by adding this

-> String

a string containing the sql to parse

-> Either ParseErrorExtra [Statement]

parseStatementsFromFile

Arguments

:: FilePath

file name of file containing sql

-> IO (Either ParseErrorExtra [Statement])

parseQueryExpr

Arguments

:: String

filename to use in errors

-> String

a string containing the sql to parse

-> Either ParseErrorExtra QueryExpr

Testing

parseScalarExpr

Arguments

-> String

-> Either ParseErrorExtra ScalarExpr

Parse expression fragment, used for testing purposes
