SQL state codes (SQL standard)

Types

type Position

type Position struct {
	Line   int // 1-based line number
	Column int // 1-based column number
}

Position represents a position in SQL text for error reporting.

type XxSqlError

type XxSqlError struct {
	Code     int            // Primary error code (1xxx-6xxx ranges)
	SubCode  int            // Secondary code for detail
	SQLState string         // SQL standard state code (5 chars)
	Message  string         // User-facing message
	Detail   string         // Technical details
	Hint     string         // Suggested fix
	Position *Position      // Line/column in SQL
	Context  map[string]any // Additional context
}

XxSqlError represents a structured error with comprehensive information.
