GoCQLX Query Builder

Package qb provides CQL query builders. The builders create CQL statement and a list of named parameters that can later be bound using gocqlx.

The following CQL commands are supported: SELECT, INSERT, UPDATE, DELETE and BATCH.

Types

type BatchBuilder 

type BatchBuilder struct {
	// contains filtered or unexported fields
}

BatchBuilder builds CQL BATCH statements.

func Batch deprecated 

func Batch() *BatchBuilder

Batch returns a new BatchBuilder. BatchBuilder encapsulates batch cqls as one ordinary gocql.Query for convenience. Below are the limitations of encapsulating batch cqls based on gocql.Query instead of gocql.Batch:

  • gocql.Batch has some more batch specific check, such as BatchSize(65535).
  • gocql.Batch use BatchObserver instead of QueryObserver.
  • gocql.Batch has cancelBatch call back.
  • gocql.Batch prepares the included statements separately, which is more efficient. In contrast, gocqlx.qb.BatchBuilder, which is based on gocql.Query, prepares the whole batch statements as one ordinary query.

Deprecated: Please use gocql.Session.NewBatch() instead.
