Question 1

go-mssqldb vs sqlx for SQL Server in Go

Accepted Answer

go-mssqldb is the underlying driver implementing database/sql, while sqlx is an extension that adds struct mapping and convenience methods. Use go-mssqldb for raw compliance, and layer sqlx on top if you need easier data handling without switching drivers.

Question 2

How to connect to Azure SQL Database with managed identity using go-mssqldb

Accepted Answer

Import the azuread package and use driver name 'azuresql' with fedauth=ActiveDirectoryMSI in the connection string. Ensure your Azure environment is configured for managed identity, and optionally specify a user ID for user-assigned identities.

Question 3

How to handle stored procedures with output parameters in go-mssqldb

Accepted Answer

Use sql.Named with sql.Out{Dest: &variable} in your ExecContext or QueryContext calls. For procedures with resultsets, read all rows first before accessing output parameters to avoid protocol errors, as shown in the README examples.

Question 4

go-mssqldb temporary tables not working

Accepted Answer

This is due to session isolation when parameters are used. Create temporary tables in a separate query without parameters, or use the workaround with explicit creation and cleanup on the same connection, as detailed in the Caveat section.

Question 5

How to enable SSL encryption with go-mssqldb

Accepted Answer

Set the encrypt parameter to 'true' in your connection string, and configure TrustServerCertificate appropriately. For production, use certificate validation; for testing, TrustServerCertificate=true can bypass checks but is insecure.

Question 6

go-mssqldb LastInsertId alternative

Accepted Answer

The driver does not support LastInsertId due to TDS protocol limits. Use the OUTPUT clause in your INSERT statements or append a SELECT SCOPE_IDENTITY() to your query, as recommended in the Important Notes.
