Extracting Table Column Names in MySQL
In PHP, there are multiple methods to retrieve the names of columns in a MySQL table:
1. DESCRIBE
The DESCRIBE command provides a detailed description of a table, including column names:
DESCRIBE my_table;
2. INFORMATION_SCHEMA
MySQL's INFORMATION_SCHEMA system database contains data about database objects. To retrieve column names using this method:
SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'my_database' AND TABLE_NAME = 'my_table';
3. SHOW COLUMNS
Another alternative is the SHOW COLUMNS command:
SHOW COLUMNS FROM my_table;
4. Grouped Concatenation
To obtain column names separated by commas in a single line:
SELECT group_concat(COLUMN_NAME) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'my_database' AND TABLE_NAME = 'my_table';
