I am using nestjs and typeorm (Mysql). I have two tables users and categories, and in category table i have a foreign key linked to userid. What i want to do is search firstName from user table while querying the category table.
I have 2 search fields category name and user name. For searching category name what i did is
const query = this.createQueryBuilder('category');
if (categoryName) {
query.andWhere('category.categoryName LIKE :categoryName', {
categoryName: `%${categoryName}%`,
});
}
And for searching username
if (userName) {
query.andWhere('category.user.firstName LIKE :userName', {
userName: `%${userName}%`,
});
}
But the above one is giving me error. Any idea how to do it using typeorm and nestjs ? Thanks for the help !
You need to join category with user first. Try something like this:
const query = this.createQueryBuilder('category');
if (categoryName) {
query.andWhere('category.categoryName LIKE :categoryName', { categoryName: `%${categoryName}%` });
}
if (userName) {
query
.leftJoinAndSelect('category.user', 'user')
.andWhere('user.firstName LIKE :userName', { userName: `%${userName}%` });
}
