Azure SQL
The Azure SQL component lets you run an SQL query on an Azure SQL database and copy the results to a table—this stages the data, so the table is reloaded each time. You can then use transformation components to enrich and manage the data in permanent tables.
If the component requires access to a cloud provider, it will use the cloud credentials associated with your environment to access resources.
Properties
Reference material is provided below for the Connect, Configure, and Destination properties.
Connect
Server Name = string
The Azure SQL server URL.
Database Name = string
The name of the database.
Authentication Type = drop-down
Currently only supports username and password.
Username = string
Your Azure SQL server connection username.
Password = drop-down
Drop-down list of secret definitions. Create a secret definition to reference your corresponding Azure SQL connection password.
To create a secret definition:
- Click Manage to open the Secret definitions tab in a new browser tab.
- Click Add secret definition.
- Name your secret definition. Names must be unique.
- Add a description if you wish. This is optional.
- Toggle Yes if using a multi-line input password. Otherwise, keep the toggle set to No.
- Add your Azure SQL password to the Secret value field.
- Click Create secret. You will return to the Secret definitions tab.
- Close the browser tab to return to Designer.
- Select your new secret definition from the drop-down menu. If the secret has not propagated, click out of the dialog and then try again.
Connection Options = column editor
- Parameter: A JDBC parameter supported by the database driver. The available parameters are explained in the data model. Manual setup is not usually required, since sensible defaults are assumed.
- Value: A value for the given parameter.
Click the Text Mode toggle at the bottom of the Connection Options dialog to open a multi-line editor that lets you add items in a single block. For more information, read Text mode.
Configure
Mode = drop-down
- Basic: This mode will build a query for you using settings from the Schema, Data Source, Data Selection, Data Source Filter, Combine Filters, and Limit parameters. In most cases, this mode will be sufficient.
- Advanced: This mode will require you to write an SQL-like query to call data from the service you're connecting to. The available fields and their descriptions are documented in the data model.
There are some special pseudo columns that can form part of a query filter, but are not returned as data. This is fully described in the data model.
Note
While the query is exposed in an SQL-like language, the exact semantics can be surprising, for example, filtering on a column can return more data than not filtering on it. This is an impossible scenario with regular SQL.
SQL Query = code editor
This is an SQL-like SELECT query, written in the SQL accepted by your cloud data warehouse. Treat collections as table names, and fields as columns. Only available in Advanced mode.
Data Source = drop-down
Select a single data source to be extracted from the source system and loaded into a table in the destination. The source system defines the data sources available. Use multiple components to load multiple data sources.
Data Selection = dual listbox
Choose one or more columns to return from the query. The columns available are dependent upon the data source selected. Move columns left-to-right to include in the query.
To use grid variables, tick the Use Grid Variable checkbox at the bottom of the Data Selection dialog.
Data Source Filter = column editor
Define one or more filter conditions that each row of data must meet to be included in the load.
- Input Column: Select an input column. The available input columns vary depending upon the data source.
- Qualifier:
- Is: Compares the column to the value using the comparator.
- Not: Reverses the effect of the comparison, so "Equals" becomes "Not equals", "Less than" becomes "Greater than or equal to", etc.
- Comparator: Choose a method of comparing the column to the value. Possible comparators include: "Equal to", "Greater than", "Less than", "Greater than or equal to", "Less than or equal to", "Like", "Null". "Equal to" can match exact strings and numeric values, while other comparators, such as "Greater than" and "Less than", will work only with numerics. The "Like" operator allows the wildcard character
%to be used at the start and end of a string value to match a column. The Null operator matches only null values, ignoring whatever the value is set to. Not all data sources support all comparators, meaning that it is likely that only a subset of the above comparators will be available to choose from. - Value: The value to be compared.
Click the Text Mode toggle at the bottom of the Connection Options dialog to open a multi-line editor that lets you add items in a single block. For more information, read Text mode.
Combine Filters = drop-down
The data source filters you have defined can be combined using either And or Or logic. If And, then all filter conditions must be satisfied to load the data row. If Or, then only a single filter condition must be satisfied. The default is And.
If you have only one filter, or no filters, this parameter is essentially ignored.
Row Limit = integer
Set a numeric value to limit the number of rows that are loaded. The default is an empty field, which will load all rows.
Destination
Select your cloud data warehouse.
Destination = drop-down
- Snowflake: Load your data into Snowflake. You'll need to set a cloud storage location for temporary staging of the data.
- Cloud Storage: Load your data directly into your preferred cloud storage location.
Click either the Snowflake or Cloud Storage tab on this page for documentation applicable to that destination type.

The Snowflake database. The special value, [Environment Default], will use the database defined in the environment. Read Databases, Tables and Views - Overview to learn more.
Schema = drop-down
The Snowflake schema. The special value, [Environment Default], will use the schema defined in the environment. Read Database, Schema, and Share DDL to learn more.
Table Name = string
The name of the table to be created.
Load Strategy = drop-down
- Replace: If the specified table name already exists, that table will be destroyed and replaced by the table created during this pipeline run.
- Truncate and Insert: If the specified table name already exists, all rows within the table will be removed and new rows will be inserted per the next run of this pipeline.
- Fail if Exists: If the specified table name already exists, this pipeline will fail to run.
- Append: If the specified table name already exists, then the data is inserted without altering or deleting the existing data in the table. It's appended onto the end of the existing data in the table. If the specified table name doesn't exist, then the table will be created, and your data will be inserted into the table. For example, if you have a source holding 100 records, then on the first pipeline run, your target table will be created and 100 rows will be inserted. On the second pipeline run, those same 100 records will be appended to your existing target table, so now it holds 200 records. Third pipeline run will be 300 records in your table, and so on.
