12 Φεβ 2024 · One effective method to check if a particular string occurs in a MySQL table is by utilizing the SELECT statement along with the LOCATE() function. The LOCATE() function in MySQL is employed to find the position of the first occurrence of a substring within a given string.
MySQL uses C escape syntax in strings (for example, \n to represent the newline character). If you want a LIKE string to contain a literal \ , you must double it. (Unless the NO_BACKSLASH_ESCAPES SQL mode is enabled, in which case no escape character is used.)
The LOCATE() function returns the position of the first occurrence of a substring in a string. If the substring is not found within the original string, this function returns 0. This function performs a case-insensitive search.
