Method parseTryCastExpression

// CAST. Snowflake, SQL Server, and BigQuery return NULL on conversion failure
// instead of raising an error.
func (p *Parser) parseTryCastExpression() (*ast.CastExpression, error) {
	return p.parseCastLike(true)
}

// parseCastLike implements the body shared between CAST and TRY_CAST. The
// caller is responsible for ensuring the current token is the leading keyword.
