![]() But based on the LEN() function you may avoid the non-valid data, then using the CONVERT you can get the VARCAHR field as DATETIME value.īased on your sample data the valid date's minimum length is 10 characters, so you can apply the condition in the WHERE clause. Update: As you mentioned in the comments the Gradd19 having the values of 20 and 60, it is difficult to filter those non-valid data. You need to use CONVERT(VARCHAR(19), CONVERT(DATETIME, Gradd19, 105), 120) AS ExpiryDate Without using the 'T' instead of the space in the datetime string, Sql Server won't recognize it as ISO8601 format. If your sql server is set to use the dateformat dmy then that explains your issue. ![]() You need to provide the PARSE function with the string value that will be converted, the target data type that the provided value will be converted to, in addition to the culture, which is an optional string that specifies the culture, any language supported by the. 4 Answers Sorted by: 9 I checked your profile and saw that you are in the UK. ![]() SELECT instead of CONVERT(VARCHAR, Gradd19, 105) AS ExpiryDate The PARSE function is used to convert the provided string expression into the requested SQL Server data type. SELECT = CONVERT(VARCHAR(19), CONVERT(DATETIME, 105), 120) SELECT in that case you need do one more conversion to skip the issue, like the below: DECLARE DATETIME NB: In some countries, for example France where I leave, it is standard practise to use a comma instead of a point. If the datatype is TEXT we have to first cast to varchar(for example) and then cast again to money. SELECT if it is in yyyy-dd-mm it will throw out-of-range value error DECLARE DATETIME SQL server will not convert directly from TEXT to money. In this tutorial, you have learned how to use the CAST() and TO_DATE() functions to convert a string to a date in SQL.Since you are not shared the sample data of the Gradd19 value, I suspect the date value is in the yyyy-dd-mm format, so when trying to convert (month value more than 12) it cause the out-of-range value error.įor sample, if the date format in yyyy-mm-dd, it will execute properly: DECLARE DATETIME Notice that the date format must be corresponding to the date string as specified in the statement DD MON YYYYĬheck it out the Oracle TO_DATE() and PostgreSQL TO_DATE() functions for the details. The following shows the TO_DATE() function syntax: TO_DATE(string, format)įor example, to convert the string '' to a date value, you use the following statement: SELECT TO_DATE( '', 'DD MON YYYY' ) Oracle and PostgreSQL provide the TO_DATE() function that converts a string to date based on a specified format. Here is the result: Code language: SQL (Structured Query Language) ( sql ) Convert string to date using TO_DATE() function Similarly, the following example also converts the string 180101 to January 1st, 2018: SELECT CAST( '180101' AS DATE) SQL Server converts the string 2018 to January 1st, 2018: The following example shows how to convert a string to a date: SELECT CAST( '2018' AS DATE) In case the function fails to convert, it issues an error, depending on the implementation of a specific database system. The CAST() function returns a DATE value if it successfully converts the string to date. In this syntax, the string can be any DATE value that is convertible to a date. The following illustrates the syntax of the CAST() function: CAST (string AS DATE)Ĭode language: SQL (Structured Query Language) ( sql ) I have looked online for a possible way to convert it without success. SQL provides a CAST() function that allows you to convert a string to a date.
