SQLcommenter is a plugin/middleware/wrapper to augment application related information/tags with SQL Statements that can be used later to correlate user code with SQL statements.

go get -u github.com/google/sqlcommenter/go/database/sql

Please use the sqlcommenter's default go-sql database driver to execute statements. Due to inherent nature of Go, the safer way to pass information from framework to database driver is via context. So, it is recommended to use the context based methods of DB interface like QueryContext, ExecContext and PrepareContext.

import (
    gosql "github.com/google/sqlcommenter/go/database/sql"
    sqlcommentercore "github.com/google/sqlcommenter/go/core"
    _ "github.com/lib/pq" // or any other database driver
)

db, err := gosql.Open("<driver>", "<connectionString>", sqlcommentercore.CommenterOptions{
    Config: sqlcommentercore.CommenterConfig{<flag>:bool}
    Tags  : sqlcommentercore.StaticTags{<tag>: string} // optional
})

Users are given control over what tags they want to append by using core.CommenterOptions struct.

type CommenterOptions struct {
    EnableDBDriver    bool
    EnableTraceparent bool   // OpenTelemetry trace information
    EnableRoute       bool   // applicable for web frameworks
    EnableFramework   bool   // applicable for web frameworks
    EnableController  bool   // applicable for web frameworks
    EnableAction      bool   // applicable for web frameworks
    EnableApplication bool   // applicable for web frameworks
}

Users can also provide static tags they want to use by using core.StaticTags struct. These tags are optional. If not provided, the Application tag will get auto-populated from the user-project's module-name in go.mod. DriverName is set to the driver-name provided in gosql.Open(driverName, ...) call.

type StaticTags struct {
    Application string
    DriverName  string
}

The driver will try to use the module-name from the project's go.mod as the application name if EnableApplication is true and no Application string is provided (works correctly for compiled go applications).

• http/net - basic support
• gorrila/mux - proper support

With Go SqlCommenter, we have configuration to choose which tags to be appended to the comment.
