Other tools you may find usefulSQL INSERT statement generator – bulk insert from CSV and form
Manually writing INSERT queries for many records is tedious and error-prone. The generator automatically creates valid INSERT INTO statements from data pasted from a spreadsheet, CSV or form, with support for various SQL dialects.
Syntax SQL INSERT
INSERT INTO table (col1, col2) VALUES (val1, val2). Bulk insert: INSERT INTO table (col1, col2) VALUES (v1,v2),(v3,v4),(v5,v6). MySQL: up to 65535 rows at a time. PostgreSQL: unlimited (virtually). SQLite: INSERT OR REPLACE INTO (upsert). INSERT INTO ... SELECT ...: copy from another table. INSERT IGNORE (MySQL): skip duplicate errors.
Escaping values in SQL
Strings: surround them with single quotes. Apostrophes in value: double: O'Connor → 'O''Connor'. Parameterized queries: more secure (?, $1, :name). NULL: no apostrophes. Numbers: without apostrophes. Dates: depends on the database. MySQL: '2024-01-15'. PostgreSQL: '2024-01-15'::date. Note: SQL injection! Never paste raw user data into SQL.
Bulk insert – performance
Bulk insert much faster than single INSERT in a loop. MySQL: INSERT INTO t VALUES (1,2),(3,4),(5,6) = one transaction. Transactions: BEGIN; INSERT; INSERT; COMMIT; – faster than autocommit. Disable indexes before bulk: ALTER TABLE t DISABLE KEYS; INSERT...; ENABLE KEYS; (MySQL). PostgreSQL: COPY is the fastest for large data. SQLite: journal_mode=WAL + one transaction.
SQL dialects - differences INSERT
MySQL: INSERT IGNORE (skip errors), INSERT ... ON DUPLICATE KEY UPDATE (upsert). PostgreSQL: INSERT ... ON CONFLICT DO NOTHING/UPDATE (upsert). SQLite: INSERT OR REPLACE / INSERT OR IGNORE. SQL Server: MERGE INTO (upsert). Oracle: MERGE INTO. Standard SQL: no built-in upsert (was from SQL:2003 as MERGE). Check your database documentation.
FAQ
How to generate INSERT from Excel/Google Sheets?
Method 1: Concatenate formula: ="INSERT INTO users (name, email) VALUES ('",A2,"','",B2,"');" Method 2: Copy → CSV → Paste to online generator. Method 3: Python pandas: df.to_sql("users", engine) or manually generate INSERT. Method 4: DBeaver/DataGrip: Import CSV directly into the table. Online generator: paste tabular data, select columns, generate.
How to safely insert data into SQL (SQL injection)?
Never: $sql = "INSERT INTO users (name) VALUES ('" . $userInput . "')". Always: prepared statements (PDO PHP: $stmt->bindParam(), Java PreparedStatement, Python cursor.execute("%s")). ORM: Eloquent, SQLAlchemy, Django ORM automatically parameterize. Validation: check the data type before inserting. Permissions: database user, INSERT only, not DROP/ALTER.
How to check how many records an INSERT inserted?
MySQL: SELECT ROW_COUNT() after INSERT. PHP PDO: $pdo->lastInsertId() (last ID). $stmt->rowCount() (number inserted). PostgreSQL: INSERT INTO ... RETURNING id (returns inserted records). JDBC Java: getUpdateCount(). Python: cursor.rowcount. Transaction:COMMIT returns the number of rows changed in some clients.
What is the difference between INSERT and UPSERT?
INSERT: insert a new record. Error if key exists (duplicate key). UPSERT (insert or update): if it exists → update, if not → insert. MySQL: INSERT INTO t VALUES (...) ON DUPLICATE KEY UPDATE col=VALUES(col). PostgreSQL: INSERT INTO t VALUES (...) ON CONFLICT (id) DO UPDATE SET col=EXCLUDED.col. Application: data synchronization, idempotent o
