In SQL, you can use the following methods to trim strings:<\/p>\n

    \n
  1. The SUBSTRING() function allows you to extract a portion of a string by specifying the starting position and length. The syntax is as follows:<\/li>\n
  2. Retrieve a specific portion of text from a column in a table by specifying the starting position and desired length.<\/li>\n
  3. The LEFT() and RIGHT() functions are used to extract a specified length of characters from the left and right side of a string, respectively. The syntax is as follows:<\/li>\n
  4. Retrieve a portion of text from a specific column in a table by specifying the number of characters from the beginning or the end.<\/li>\n
  5. The MID() function is used to extract a specified number of characters from a string, starting at a specific position. The syntax is as follows:<\/li>\n
  6. Retrieve a substring from a specified column in a table starting from a certain position and with a specified length.<\/li>\n
  7. The SUBSTR() function is used to extract a specified length of characters starting from a specified position in a string. The syntax is as follows:<\/li>\n
  8. Retrieve a portion of the data from a specific column in a table by specifying the starting position and length.<\/li>\n<\/ol>\n

    The above are commonly used string truncation methods, and you can choose the appropriate method based on specific requirements during actual use.<\/p>\n","protected":false},"excerpt":{"rendered":"
