This example displays a date and time as character data, uses CAST to change the character data to the datetime data type, and then uses CONVERT to change the character data to the datetime data type. I'd agree with you when specifying database schema (especially stored procedure parameters). the time portion: If you want to convert a "date-like" number to a date, such as the Internally, the CAST function and the :: operator call the appropriate conversion Other values are processed as 0. practical examples about different scenarios using different solutions for ways Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"?
