Usage Suggestions

Helpful suggestions for Table Relationship Mapper

Use Table Relationship Mapper as a browser-side helper for drafting, reviewing, or converting SQL. Verify important output in a staging database before production use.

Pick the dialect

Choose MySQL, PostgreSQL, SQLite, SQL Server, or Oracle before copying syntax-sensitive output.

Review identifiers

Quote or rename reserved words and columns with spaces before running generated SQL.

Prefer parameters

Use the parameterized output for application code and never concatenate user input into SQL strings.

Test safely

Run DDL/DML output on staging data first, especially UPDATE, DELETE, ALTER TABLE, backup, and migration helpers.
