Different applications and solutions use different start dates. In your case your number appears to be based on a start date of. This is normally a count of days from a start date. To convert the date time to a number in MySQL, the syntax is as follows − SELECT UNIX_TIMESTAMP(yourColumnName) as anyVariableName FROM yourTableName To understand the above syntax, let us create a table.ĭo you want a number like YYYYMMDD or the integer portion of SQL's internal date or ?SELECT CAST(CONVERT(VARCHAR(8), CURRENT_TIMESTAMP, 112) AS INT) SELECT CAST(CURRENT_TIMESTAMP AS INT)- etc. How to convert timestamp to integer in sql To change the format of the date, you convert the requested date to a string and specify the format number corresponding to the format needed. If a universal date/time is needed, then getutcdate() should be used. This provides the current date and time according to the server providing the date and time. There is no implicit conversion on assignment from the sql_variant data type, but there is implicit conversion to sql_variant. These include bigint, and sql_variant, and xml. The following illustration shows all explicit and implicit data type conversions allowed for SQL Server system-supplied data types. The following example shows the results of converting a time(4) value to a time(3) value. When the destination precision is less than the source precision, the fractional seconds is rounded up to fit the destination precision. When the conversion is to time(n), the hour, minute, and seconds are copied. Converting the string to a datetime with a specific file format takes care of that problem. ![]() TIME_TO_SEC () function MySQL TIME_TO_SEC () converts a time value in to seconds.Īs a result, SQL cannot guarantee that the implicit conversion will always end up with the same result. We are adding all the seconds together so that we will get the correct seconds output. The second to_char function will convert hours in to seconds and third to_char function can calculate minutes in seconds. The TIME_TO_SEC() function converts a time value into seconds. This is achieved by using the time (n) syntax, where n is the scale from 0 to 7. The time data type, on the other hand, allows you to specify a fractional seconds precision from 0 to 7. Its accuracy is rounded to increments of.000.003, or.007 seconds. ![]() ![]() The datetime data type has a maximum of 3 digits for its fractional seconds part. 5 Hijri is a calendar system with several variations. For conversion from datetime or smalldatetime to character data, see the previous table for the output format. 3 Input when you convert to datetime output when you convert to character data.
