Functions ¶
func DefaultOps ¶
DefaultOps returns a default map of SLQ operator (e.g. "==" or "!=") to its SQL rendering. The returned map is a copy and can be safely modified by the caller.
Types ¶
type Dialect ¶
type Dialect struct {
// Type is the dialect's driver type.
Type source.DriverType `json:"type"`
// Placeholders returns a string a SQL placeholders string.
// For example "(?, ?, ?)" or "($1, $2, $3), ($4, $5, $6)".
Placeholders func(numCols, numRows int) string
// Enquote is a function that quotes and escapes an
// identifier (such as a table or column name). Typically the func
// uses the double-quote rune (although MySQL uses backtick).
Enquote func(string) string
// IntBool is true if BOOLEAN is handled as an INT by the DB driver.
IntBool bool `json:"int_bool"`
// MaxBatchValues is the maximum number of values in a batch insert.
MaxBatchValues int
// Ops is a map of overridden SLQ operator (e.g. "==" or "!=") to
// its SQL rendering.
Ops map[string]string
// Joins is the set of JOIN types (e.g. "RIGHT JOIN") that
// the dialect supports. Not all drivers support each join type. For
// example, MySQL doesn't support jointype.FullOuter.
Joins []jointype.Type
}
Dialect holds driver-specific SQL dialect values and functions.
