Why migrate ParadeDB to SQL Server?

Teams switch when reporting, BI tooling, or corporate standards require SQL Server.Galaxy users often consolidate analytics in one place.

What preparatory checks are essential?

Confirm ParadeDB version, enable ANSI-compatible identifiers, and validate that table names, data types, and sequences map to SQL Server equivalents.

Which tools streamline the move?

Use pg_dump for exports, SQL Server Migration Assistant (SSMA) for schema translation, and BULK INSERT or bcp for data loads.

How do I export ParadeDB schema only?

Run pg_dump -Fc --schema-only -f paradedb_schema.dump parade_prod.A custom format is easiest for SSMA to parse.

How to convert PostgreSQL types to SQL Server?

In SSMA, map serial → INT IDENTITY, boolean → BIT, and jsonb → NVARCHAR(MAX) or SQL_VARIANT.

How do I dump data as CSV?

Export each table with copy commands; Galaxy snippets below suit an ecommerce dataset.

CSV export for Customers

\copy Customers TO 'customers.csv' CSV HEADER

CSV export for Orders

\copy Orders TO 'orders.csv' CSV HEADER

What’s the import flow in SQL Server?

Create empty tables via SSMA, then run BULK INSERT statements to load CSVs.

BULK INSERT example

BULK INSERT dbo.Customers FROM 'C:\data\customers.csv' WITH (FORMAT='CSV', FIRSTROW=2);

How do I maintain referential integrity?

Disable CHECK and FOREIGN KEY constraints during load: ALTER TABLE Orders NOCHECK CONSTRAINT ALL; Re-enable after loading.

Best practices for large tables?

Chunk data into 1 GB files, use TABLOCK and BATCHSIZE options, and rebuild indexes afterward.

How can Galaxy accelerate migration?

Galaxy AI copilot generates conversion scripts, validates row counts, and shares endorsed queries across teams.

Where to verify success?

Run count comparisons: SELECT COUNT(*) FROM Customers; in both systems.Use Galaxy’s side-by-side query tabs.

How to Migrate from ParadeDB to SQLServer in PostgreSQL Example Usage


-- Verify migrated totals in Galaxy
SELECT
    (SELECT COUNT(*) FROM dbo.Customers)     AS customers_cnt,
    (SELECT COUNT(*) FROM dbo.Orders)        AS orders_cnt,
    (SELECT COUNT(*) FROM dbo.Products)      AS products_cnt,
    (SELECT COUNT(*) FROM dbo.OrderItems)    AS order_items_cnt;

How to Migrate from ParadeDB to SQLServer in PostgreSQL Syntax


-- 1. Export ParadeDB schema in custom format
pg_dump -Fc --schema-only \
        --no-owner --no-privileges \
        --file=paradedb_schema.dump parade_prod

-- 2. Export data as CSV per table
\copy Customers  TO 'customers.csv'  CSV HEADER
\copy Orders     TO 'orders.csv'     CSV HEADER
\copy Products   TO 'products.csv'   CSV HEADER
\copy OrderItems TO 'order_items.csv' CSV HEADER

-- 3. Create target DB in SQL Server
CREATE DATABASE Parade_Migrated;
GO

-- 4. Run SSMA to convert paradedb_schema.dump into T-SQL and apply
-- 5. Import data in SQL Server
BULK INSERT dbo.Customers
FROM 'C:\data\customers.csv'
WITH (FORMAT='CSV', FIRSTROW=2, TABLOCK, BATCHSIZE=10000);

BULK INSERT dbo.Orders
FROM 'C:\data\orders.csv'
WITH (FORMAT='CSV', FIRSTROW=2, TABLOCK, BATCHSIZE=10000);

-- 6. Re-enable constraints and compare row counts

Common Mistakes

Running pg_dump with INSERT format. INSERT scripts choke on SQL Server’s 2 GB limit per batch. Use CSV and BULK INSERT instead.
Leaving constraints enabled during import. This slows loads and causes FK violations. Disable, load, then re-enable.

Frequently Asked Questions (FAQs)

Is ParadeDB fully PostgreSQL-compatible for pg_dump?

Yes. ParadeDB follows PostgreSQL wire protocol, so pg_dump works unchanged.

Can I automate type mappings in SSMA?

Create a custom mapping file in SSMA and reuse it for multiple projects.

How do I migrate sequences?

SSMA converts serial columns to IDENTITY. For standalone sequences, script them as tables with IDENTITY or use DBCC CHECKIDENT after load.
