Code & Data Generator
How PostgreSQL column types map to their SQL Server equivalents, with migration notes for each type.
| PostgreSQL Type | SQL Server Equivalent | Notes |
|---|---|---|
| SERIAL | INT IDENTITY(1,1) | SQL Server identity column syntax |
| BIGSERIAL | BIGINT IDENTITY(1,1) | — |
| BOOLEAN / BOOL | BIT | SQL Server boolean type; 0=false, 1=true |
| TEXT | NVARCHAR(MAX) | Use NVARCHAR(MAX) for unlimited Unicode text |
| VARCHAR(n) | NVARCHAR(n) | Use NVARCHAR for Unicode support |
| BYTEA | VARBINARY(MAX) | — |
| TIMESTAMP | DATETIME2 | DATETIME2 has higher precision than DATETIME |
| TIMESTAMP WITH TIME ZONE | DATETIMEOFFSET | Preserves timezone offset |
| JSONB / JSON | NVARCHAR(MAX) | SQL Server 2016+ has JSON functions; no native JSON column type |
| UUID | UNIQUEIDENTIFIER | SQL Server native GUID type; use NEWID() |
| DOUBLE PRECISION | FLOAT | SQL Server FLOAT is 64-bit by default |
| REAL | REAL | Same name; 32-bit float |
| SERIAL PRIMARY KEY | INT IDENTITY(1,1) PRIMARY KEY | — |
| NUMERIC(p,s) / DECIMAL(p,s) | NUMERIC(p,s) / DECIMAL(p,s) | Same syntax |
Everything you need to know about converting PostgreSQL to SQL Server.
Paste your PostgreSQL CREATE TABLE statements into the SQL editor on the left. The SQL Server output appears instantly on the right panel in real-time as you type.
Yes — completely. The entire conversion runs inside your browser using JavaScript. Your SQL is never sent to any server, logged, or stored anywhere. This makes it safe to use with production or confidential database schemas.
PostgreSQL, MySQL, SQLite, SQL Server, Oracle, and MariaDB DDL syntax are all supported. The parser auto-detects the dialect from your CREATE TABLE syntax automatically.
Yes! Paste multiple CREATE TABLE statements separated by semicolons and all tables will be converted simultaneously, including cross-table foreign key relationships.
Yes. NULL, NOT NULL, DEFAULT values, PRIMARY KEY, UNIQUE, and FOREIGN KEY constraints are all parsed and reflected in the SQL Server output. Nullable columns are correctly typed as optional properties or nullable types.
Yes, SchemaForge is completely free with no usage limits, no account required, and no rate limits. The tool runs entirely in your browser and will always be free.
