Bob Executors

While it is enough to use a bob.Executor for queries, for a full application, there are other things needed.

  • Ability to ping the database for health checks
  • Ability to start transactions with *sql.DB
  • Ability to commit/rollback with *sql.Tx
  • Ability to prepare and reuse statements

For these purposes, bob has concrete DB, Tx and Conn structs that wrap the database/sql equivalents but implement the bob.Executor interface too.

See the reference for these types:

bob.DB​

Reference

Convert an existing *sql.DB to bob.DB with bob.NewDB()

Open a DB connection and return bob.DB with bob.Open(). This is the same as running sql.Open() and then bob.NewDB().

bob.Tx​

Reference

Convert an existing *sql.Tx to bob.Tx with bob.NewTx()

bob.Conn​

Reference

Convert an existing *sql.Conn to bob.Conn with bob.NewConn()

Prepared Statements​

All of the above executors can be used to create prepared statements too.
