Types

type Client 

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

func New 

func New(cfg Config) (*Client, error)

func NewWithDB 

func NewWithDB(db *sql.DB, cfg Config) (*Client, error)

NewWithDB constructs a Client from an existing *sql.DB. This is mainly useful for tests where we use a sqlmock.DB.

func (*Client) Close 

func (c *Client) Close() error

func (*Client) DescribeTable 

func (c *Client) DescribeTable(ctx context.Context, database, table string) ([]map[string]any, error)

func (*Client) ListDatabases 

func (c *Client) ListDatabases(ctx context.Context) ([]string, error)

func (*Client) ListTables 

func (c *Client) ListTables(ctx context.Context, database string) ([]string, error)

func (*Client) RunQuery 

func (c *Client) RunQuery(ctx context.Context, sqlText string, maxRows int) ([]map[string]any, error)

RunQuery is intentionally “read oriented” – callers should enforce SELECT only.

type Config 

type Config struct {
	DSN             string
	MaxRows         int
	QueryTimeoutS   int
	MaxOpenConns    int
	MaxIdleConns    int
	ConnMaxLifetime time.Duration
	ConnMaxIdleTime time.Duration
	PingTimeout     time.Duration
}
