Getting rows of a table based on query on another table

I have these 2 tables

[Products]
ID
CompanyID,
Name,
PartNo,
IDSGroup,
ChartNo

[Company]
ID,
Name,
RegistrationNo,
RegistrationDate

I want to show these columns from tables when user search for a company name:

Company.Name, Product.Name, Product.PartNo, Product.IDSGroup

This search query let me get the CompanyID

Select Company.ID from Company WHERE Company.Name LIKE "$userSearch%"

Now I want to use Company.ID for this query to get all product

Select * from Products WHERE CompanyID = "id from previous query"
Solution

  • If it's in the same database you can just join the two tables

    SELECT
Company.Name, Products.Name, Products.PartNo, Products.IDSGroup
FROM
Company
LEFT JOIN Products
ON Company.ID = Products.CompanyID
WHERE
Company.Name LIKE "$userSearch%"
