When you need this
  • A stakeholder emails you a list of customer IDs in Excel and you need to query them in your database.
  • You have a CSV export and need to check which rows are still present in the database.
  • You need to delete or update a specific set of records by ID.
  • Your IN clause has more than 1000 values and the database returns an error (Oracle limit).
How to do it with Daily Developer Tools
  • Paste your list of IDs or values — one per line, or comma-separated — into the SQL IN Clause Builder.
  • Choose whether to quote the values (for string columns) and whether to deduplicate.
  • Set a chunk size if your database limits IN clause length.
  • Copy the generated WHERE customer_id IN (1, 2, 3, ...) clause into your query.
Tips / common pitfalls
  • For numeric IDs, leave quoting off to avoid implicit type conversion overhead.
  • Oracle limits IN clauses to 1000 items — use chunking to split into multiple clauses joined with OR.
  • Deduplicate before building the clause to avoid unnecessary query load.
  • NOT IN with NULL values in the list returns no rows — if your column can be NULL, use NOT EXISTS instead.

FAQ
How do I handle string values?

Enable the Quote values toggle to wrap each item in single quotes. This is required for VARCHAR/TEXT columns but should be avoided for integer columns to prevent type coercion.

What is chunking?

Oracle and some other databases reject IN clauses with more than 1000 items. Chunking splits your list into multiple IN clauses of the configured size, which you join with OR in your WHERE clause.

Can I generate NOT IN?

Yes, toggle NOT IN. Be cautious: if any value in the list is NULL, NOT IN returns zero rows for all comparisons. Use NOT EXISTS for nullable columns to avoid this pitfall.

How to generate a SQL IN clause from a list

Paste your list of values (one per line or comma-separated), configure quoting and deduplication options, and copy the generated IN clause. The tool handles trimming, escaping single quotes in string values, and chunking large lists automatically.

Common use cases

Data engineers use this daily to translate exported lists from business stakeholders into SQL WHERE conditions. Developers use it during data migrations to check which rows need processing. QA teams use it to build targeted cleanup queries against staging databases.
