70+
71+
2. **Create Sample Tables**: Use the following script to create tables with spaces in their names and columns. Click [here to see the .sql file](https://github.com/MicrosoftCloudEssentials-LearningHub/Demos-ScenariosHub/blob/main/0_Azure/2_AzureAnalytics/1_SynapseAnalytics/demos/2_synapse_views_dynamically_remove_space/1_dedicatedSQLPoolStoreProc/src/create-sample-tables.sql).
72+
73+
```sql
74+
-- Create sample tables with spaces in names
75+
CREATE TABLE [Employee Records] (
76+
[Employee ID] INT,
77+
[Employee Name] NVARCHAR(255),
78+
[Employee Address] NVARCHAR(255)
79+
);
80+
81+
CREATE TABLE [Sales Data] (
82+
[Sale ID] INT,
83+
[Sale Date] DATE,
84+
[Employee ID] INT,
85+
[Sale Amount] DECIMAL(10, 2)
86+
);
87+
88+
CREATE TABLE [Inventory Details] (
89+
[Item ID] INT,
90+
[Item Name] NVARCHAR(255),
91+
[Item Category] NVARCHAR(255),
92+
[Item Price] DECIMAL(10, 2)
93+
);
94+
95+
-- Insert sample data into the tables
96+
INSERT INTO [Employee Records] ([Employee ID], [Employee Name], [Employee Address])
97+
VALUES (1, 'Alice Johnson', '789 Pine St');
98+
99+
INSERT INTO [Employee Records] ([Employee ID], [Employee Name], [Employee Address])
100+
VALUES (2, 'Bob Brown', '101 Maple St');
101+
102+
INSERT INTO [Sales Data] ([Sale ID], [Sale Date], [Employee ID], [Sale Amount])
103+
VALUES (1, '2023-02-01', 1, 200.00);
104+
105+
INSERT INTO [Sales Data] ([Sale ID], [Sale Date], [Employee ID], [Sale Amount])
106+
VALUES (2, '2023-02-02', 2, 250.00);
107+
108+
INSERT INTO [Inventory Details] ([Item ID], [Item Name], [Item Category], [Item Price])
109+
VALUES (1, 'Gadget', 'Electronics', 49.99);
110+
111+
INSERT INTO [Inventory Details] ([Item ID], [Item Name], [Item Category], [Item Price])
112+
VALUES (2, 'Tool', 'Hardware', 29.99);
113+

116+
117+
3. **Run the Script**: Execute the script in the SQL script editor to create the tables and insert sample data.
118+

126+
### Create Views with Modified Tables/Column Names
127+
128+
1. **Create a Stored Procedure to Remove Spaces from Column Names**: Use the following script to create a stored procedure that removes spaces from column names and creates views. Click [here to see the .sql file](https://github.com/MicrosoftCloudEssentials-LearningHub/Demos-ScenariosHub/blob/main/0_Azure/2_AzureAnalytics/1_SynapseAnalytics/demos/2_synapse_views_dynamically_remove_space/1_dedicatedSQLPoolStoreProc/src/store-procedure-clean-up.sql).

160+
CREATE TABLE #ColumnNames (COLUMN_NAME NVARCHAR(255))
161+
INSERT INTO #ColumnNames

SELECT COLUMN_NAME

176+
BEGIN
177+
SET @sql = @sql + 'REPLACE([' + @columnName + '], '' '', '''') AS [' + REPLACE(@columnName, ' ', '') + '] '
178+
END
179+
ELSE
180+
BEGIN
181+
SET @sql = @sql + 'REPLACE([' + @columnName + '], '' '', '''') AS [' + REPLACE(@columnName, ' ', '') + '], '
182+
END
183+
184+
DELETE FROM #ColumnNames WHERE COLUMN_NAME = @columnName
185+
END
186+
187+
-- Remove the trailing comma and space if any
188+
IF RIGHT(@sql, 2) = ', '
189+

END TRY
202+
BEGIN CATCH
203+
PRINT 'Error: ' + ERROR_MESSAGE()
204+
END CATCH
205+
206+
DELETE FROM #TableNames WHERE TABLE_NAME = @tableName
207+
END
208+
209+
-- Clean up temporary tables
210+
DROP TABLE #TableNames
211+
DROP TABLE #ColumnNames
212+
END
213+
```
