tsvector

README

go-tsvector

• Postgres tsvector type definition for Go
• Tested to work with database/sql and GORM
• Compatible with any driver respecting the Scanner and Valuer interfaces.

Examples

SQL scan with casting

var out tsvector.TSVector
_ = sqlDB.QueryRow("SELECT $1::tsvector", "The quick brown fox jumps over the lazy dog").Scan(&out)

SQL scan while calling the to_tsvector function

var out tsvector.TSVector
_ = sqlDB.QueryRow("SELECT to_tsvector($1)", "The quick brown fox jumps over the lazy dog").Scan(&out)

Gorm support

type MyModel struct {
	ID  int64             `gorm:"primaryKey"`
	TSV tsvector.TSVector `gorm:"not null"`
}

in := &MyModel{
  TextTSV: tsvector.ToTSVector("The quick brown fox jumps over the lazy dog"),
}
_ = gormDB.Create(in)

var out MyModel
_ = gormDB.First(&out, in.ID)
