Functions

func ExprToExpression

func ExprToExpression(ctx *sql.Context, e sqlparser.Expr) (sql.Expression, error)

func ExpressionToColumnDefaultValue

func ExpressionToColumnDefaultValue(ctx *sql.Context, inputExpr sql.Expression, isLiteral bool) (*sql.ColumnDefaultValue, error)

ExpressionToColumnDefaultValue takes in an Expression and returns the equivalent ColumnDefaultValue if the expression is valid for a default value. If the expression represents a literal (and not an expression that returns a literal, so "5" rather than "(5)"), then the parameter "isLiteral" should be true.

func MustStringToColumnDefaultValue

func MustStringToColumnDefaultValue(ctx *sql.Context, exprStr string, outType sql.Type, nullable bool) *sql.ColumnDefaultValue

MustStringToColumnDefaultValue is used for creating default values on tables that do not go through the analyzer. Does not handle function nor column references.

func Parse

func Parse(ctx *sql.Context, query string) (sql.Node, error)

Parse parses the given SQL sentence and returns the corresponding node.

func ParseColumnTypeString

func ParseColumnTypeString(ctx *sql.Context, columnType string) (sql.Type, error)

ParseColumnTypeString will return a SQL type for the given string that represents a column type. For example, giving the string `VARCHAR(255)` will return the string SQL type with the internal type set to Varchar and the length set to 255 with the default collation.

func StringToColumnDefaultValue

func StringToColumnDefaultValue(ctx *sql.Context, exprStr string) (*sql.ColumnDefaultValue, error)

StringToColumnDefaultValue takes in a string representing a default value and returns the equivalent Expression.

func TableSpecToSchema

func TableSpecToSchema(ctx *sql.Context, tableSpec *sqlparser.TableSpec) (sql.Schema, error)

TableSpecToSchema creates a sql.Schema from a parsed TableSpec
