SQL UPDATE Generator input

Table name

A table identifier, optionally qualified by a schema. Identifiers are quoted for the selected dialect.

Column/value assignments

WHERE conditions

Add typed conditions. Multiple conditions are joined with AND.

SQL dialect

Without WHERE conditions, the generated UPDATE affects all rows. The result displays an all-rows warning.

Review generated SQL before use. Prefer prepared statements and parameterized queries for application data. These tools do not execute SQL or connect to a database.

Literal interpretation assumes PostgreSQL standard_conforming_strings=on, MySQL default backslash escaping with ANSI_QUOTES off, and SQL Server quoted identifiers. Session modes and collations are not inspected.

SQL UPDATE statement

Your result will appear here after you generate. Editing an input clears the previous result.

Processed locally in your browser. Inputs and results are not uploaded or saved by this page.

What does this tool do?

Build a SQL UPDATE statement with typed assignments and explicit WHERE conditions. Inputs: Table name, Column/value assignments, WHERE conditions, SQL dialect. Outputs: SQL UPDATE statement.

How to use it

Set the table, add typed column assignments and optional AND-joined conditions. Choose “Generate”. Copy copies the exact visible result value. Clear removes all inputs and results and restores initial options.

All processing is local and never executes SQL or connects to a database. Dialect-aware tools support documented subsets of PostgreSQL, MySQL, SQLite and SQL Server. INSERT extraction accepts explicit-column literal VALUES only, not arbitrary queries. Connection tools support PostgreSQL/MySQL URIs and SQL Server ADO.NET strings without testing credentials. Prefer parameterized queries or prepared statements when executing SQL in an application.
