Functions ¶

func ParseExpression ¶

func ParseExpression(expr string) (node ast.ExprNode, err error)

ParseExpression parses an ExprNode from a string. When TiDB loads infoschema from TiKV, `GeneratedExprString` of `ColumnInfo` is a string field, so we need to parse it into ast.ExprNode. This function is for that.

func SimpleResolveName ¶

func SimpleResolveName(node ast.ExprNode, tblInfo *model.TableInfo) (ast.ExprNode, error)

SimpleResolveName resolves all column names in the expression node.
