Title: Share Creation in Snowflake
Author: user
in snowflake database system, i have been asked to "ADD SHARE from MKAN "HTGXNLD.AUTONATION" to "HTGXNLD.AN""

Author: ChatGPT
In Snowflake, **shares** are used to enable data sharing between accounts. The instruction you received, "ADD SHARE from MKAN `HTGXNLD.AUTONATION` to `HTGXNLD.AN`," suggests adding a share from one account (`MKAN`) to another database or schema (`HTGXNLD.AN`) within the Snowflake system. However, this needs clarification as the **syntax** and exact operation may differ based on context. Here's how you can interpret and potentially implement this:

### Step-by-Step Implementation

#### 1. **Verify the Share Exists**
   Ensure the share `HTGXNLD.AUTONATION` exists in the `MKAN` account.
   ```sql
   SHOW SHARES;
   ```

#### 2. **Create a Database from the Share**
   To use a share, you typically create a database from it. If `HTGXNLD.AN` is a new database to be associated with the share:
   ```sql
   CREATE DATABASE "HTGXNLD.AN"
   FROM SHARE "MKAN"."HTGXNLD.AUTONATION";
   ```

#### 3. **Grant Permissions (If Required)**
   If you need to grant specific permissions to a role for this database:
   ```sql
   GRANT USAGE ON DATABASE "HTGXNLD.AN" TO ROLE <role_name>;
   ```

#### 4. **Add Share (If it Involves Granting a New Share)**
   If "ADD SHARE" means enabling another Snowflake account to access `HTGXNLD.AN`, you might be setting up a new share. Create a share and add objects to it:
   ```sql
   CREATE SHARE "NEW_SHARE_NAME";
   GRANT USAGE ON DATABASE "HTGXNLD.AN" TO SHARE "NEW_SHARE_NAME";
   ```

#### 5. **Clarify the Terminology**
   - If `HTGXNLD.AUTONATION` is already a shared database and `HTGXNLD.AN` is meant to consume it, step 2 suffices.
   - If you are sharing the contents of `HTGXNLD.AN` back to another account, you will need to **create a new share** and assign permissions.

---

### Summary
The phrase "ADD SHARE from MKAN `HTGXNLD.AUTONATION` to `HTGXNLD.AN`" seems to involve creating a database from an existing share. However, clarify with your team if it means creating or updating permissions for another account to access these resources.
