When working with SQL databases, there are several common commands you can use to interact with your data. Here are some of the most frequently used SQL commands:
-
SELECT: Retrieve data from one or more tables.
SELECT column1, column2 FROM table_name; -
INSERT: Add new records to a table.
INSERT INTO table_name (column1, column2) VALUES (value1, value2); -
UPDATE: Modify existing records in a table.
UPDATE table_name SET column1 = value1 WHERE condition; -
DELETE: Remove records from a table.
DELETE FROM table_name WHERE condition; -
CREATE TABLE: Create a new table in the database.
CREATE TABLE table_name ( column1 datatype, column2 datatype, ... ); -
DROP TABLE: Delete a table and its data from the database.
DROP TABLE table_name; -
ALTER TABLE: Modify an existing table structure.
ALTER TABLE table_name ADD column_name datatype; -
WHERE: Filter records based on specific conditions.
SELECT * FROM table_name WHERE condition; -
ORDER BY: Sort the result set in ascending or descending order.
SELECT * FROM table_name ORDER BY column1 ASC|DESC; -
GROUP BY: Group rows that have the same values in specified columns into summary rows.
SELECT column1, COUNT(*) FROM table_name GROUP BY column1; -
JOIN: Combine rows from two or more tables based on a related column.
SELECT columns FROM table1 JOIN table2 ON table1.common_column = table2.common_column;
These commands will help you perform a variety of operations on your SQL database. If you have specific tasks in mind, let me know, and I can provide more tailored commands!
SELECT column1, column2 FROM table_name;
INSERT INTO table_name (column1, column2) VALUES (value1, value2);
UPDATE table_name SET column1 = value1 WHERE condition;
DELETE FROM table_name WHERE condition;
CREATE TABLE table_name (
column1 datatype,
column2 datatype,
...
);
DROP TABLE table_name;
ALTER TABLE table_name ADD column_name datatype;
SELECT * FROM table_name WHERE condition;
SELECT * FROM table_name ORDER BY column1 ASC|DESC;
SELECT column1, COUNT(*) FROM table_name GROUP BY column1;
SELECT columns FROM table1 JOIN table2 ON table1.common_column = table2.common_column;

how about just a list of all the columns
Cursor
To get a list of all the columns in the summer_notes_v1 table, you can use the following SQL command, which varies slightly depending on the database system you are using. Here are examples for some common SQL databases:
-
For MySQL:
SHOW COLUMNS FROM summer_notes_v1; -
For PostgreSQL:
SELECT column_name FROM information_schema.columns WHERE table_name = 'summer_notes_v1'; -
For SQLite:
PRAGMA table_info(summer_notes_v1); -
For SQL Server:
SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'summer_notes_v1';
Choose the command that corresponds to the SQL database you are using, and it will return a list of all the columns in the summer_notes_v1 table. If you need help with a specific database, let me know!
SHOW COLUMNS FROM summer_notes_v1;
SELECT column_name
FROM information_schema.columns
WHERE table_name = 'summer_notes_v1';
PRAGMA table_info(summer_notes_v1);
SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'summer_notes_v1';
