Types ¶
type Dialect ¶
type Dialect struct {
schema.BaseDialect
// contains filtered or unexported fields
}
func New ¶
func New(opts ...DialectOption) *Dialect
func (*Dialect) AppendSequence ¶
AppendSequence adds AUTOINCREMENT keyword to the column definition. As per documentation, AUTOINCREMENT is only valid for INTEGER PRIMARY KEY, and this method will be a noop for other columns.
Because this is a valid construct:
CREATE TABLE ("id" INTEGER PRIMARY KEY AUTOINCREMENT);
and this is not:
CREATE TABLE ("id" INTEGER AUTOINCREMENT, PRIMARY KEY ("id"));
AppendSequence adds a primary key constraint as a *side-effect*. Callers should expect it to avoid building invalid SQL. SQLite also does not support AUTOINCREMENT column in composite primary keys.
func (*Dialect) DefaultSchema ¶
DefaultSchemaName is the "schema-name" of the main database. The details might differ from other dialects, but for all means and purposes "main" is the default schema in an SQLite database.
func (*Dialect) DefaultVarcharLen ¶
func (*Dialect) IdentQuote ¶
type DialectOption ¶
type DialectOption func(d *Dialect)
func WithoutFeature ¶
func WithoutFeature(other feature.Feature) DialectOption
