Types ¶
type BaseParser ¶
type BaseParser struct {
// contains filtered or unexported fields
}
BaseParser provides common functionality for dialect parsers.
func NewBaseParser ¶
func NewBaseParser(dialect grammars.Dialect) *BaseParser
NewBaseParser creates a new BaseParser for the given dialect.
func (*BaseParser) Dialect ¶
func (b *BaseParser) Dialect() grammars.Dialect
Dialect returns the dialect of the parser.
type Column ¶
type Column struct {
Name string `@Ident`
Type string `@Ident`
Constraint string `(@("PRIMARY" "KEY") | "NOT" "NULL" | "UNIQUE")?`
}
Column represents a table column
type Constraint ¶
type Constraint struct {
Type string `(@Ident ("KEY" | @Ident?) | "NOT" "NULL" | "UNIQUE")`
}
Constraint represents a column constraint
type CreateTable ¶
type CreateTable struct {
Keyword string `@"CREATE"`
Table string `@"TABLE"`
Name string `@Ident`
Columns []*Column `"(" @@ ("," @@)* ")"`
}
CreateTable represents a parsed CREATE TABLE statement
type DialectParser ¶
type DialectParser interface {
ParseDDL(ctx context.Context, sql string) (*model.Catalog, error)
Validate(sql string) ([]string, error)
Dialect() grammars.Dialect
}
DialectParser defines the interface for parsing SQL dialects
