In Oracle, the LIKE operator can be used to determine if a field contains a certain value.<\/p>\n

SELECT *\r\nFROM tableName\r\nWHERE columnName LIKE '%X%';\r\n<\/code><\/pre>\n
The above statement will return all records containing the value X.<\/p>\n
    \n
  1. % is a wildcard that can match any character, including zero characters.<\/li>\n
  2. To match values starting with X, use X%.<\/li>\n
  3. To match values that end with X, you can use %X.<\/li>\n
  4. To match the occurrence of X in the middle of field A, you can use %X%.<\/li>\n<\/ol>\n
    Please note that the LIKE operator is case-sensitive. If you want to ignore case when matching, you can use the LOWER() or UPPER() functions to convert the field and values to the same case. For example:<\/p>\n
    SELECT *\r\nFROM tableName\r\nWHERE LOWER(columnName) LIKE LOWER('%X%');\r\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
