# gosqlcrud
A Go library to work with SQL database using standard `database/sql` api. It supports SQL to array/maps/structs, and CRUD operations on structs.
# Installation
`go get -u github.com/elgs/gosqlcrud`
## Example
Please note for `Exec`, `QueryToArrays`, `QueryToMaps`, `QueryToStructs`, you are responsible for preventing SQL injection in the SQL queries. For `Retrieve`, `Create`, `Update`, `Delete`, the library will take care of it.
