![]() step5: Divide USD Amount with result from step 4Īny help is appreciated. A local SQL Server temp table is only visible to the current session. SQL temp tables are created in the tempdb database. step4: Get conversion rate for **DestinationCurrency** Local SQL Server temp tables are created using the pound symbol or hashtag followed by the table name. Servers, databases, and database objects, such as tables, views, columns, indexes, triggers, procedures, constraints, and rules, can have identifiers. Everything in Microsoft SQL Server can have an identifier. When defining the table you would need to specify an alias with the key parameter. step3 : Multiply with amount (Here we have USD value for amount) The database object name is referred to as its identifier. step2 : Get conversition rate for **Amountcurrency** using select query to table2 I was thinking to have a loop like, While (Select Count(*) From Table1) > 0 Step 1: Select database export method to custom: Step 2: Please make sure to check truncate table before insert in data creation options: Now you are able to import this database successfully. What is the best way to iterate Table1 rows and do the conversion and update it in CalculateAmountInDestinationCurrency column. CAUTION: Dont use this solution if you want to maintain existing records in your table. My Table1 has around 10000 rows and Table2 has conversion rate for all the currencies for all dates till now. Since we want to convert it to CAD get conversion rate for 1 CAD on given conversion_date, 1 CAD = 0.9399380000 USD, now we need to convert 1.60752 USD to CAD that can be done by dividing it with CAD rate i.e 1.60752/1.60752 = 1.71024 CAD. something like, select Rate from Table1 where converstion_Date = '' and Currency = 'INR'.Ībove query will give me 0.0160752000 and we will convert INR TO USD i.e As per math I will get conversation rate for 1 INR on given conversion_date from Table2 multiple it by AmountCurrency. Poorly-named tables and other objects make it difficult to maintain databases. ![]() Ĭonvert Amount from amountCurrency to destination currency and update it in last column of Table1Įxample : Amount in row one of Table1 is in INR and I want to convert it to CAD. SQL naming conventions for tables, and all the associated objects such as indexes, constraints, keys and triggers, are important for teamwork. For more information, see Number Functions in Tableau Help.ĬauseThe "#" displays instead of data when there is not enough space to display all of the data.I have two tables, Table1 with amount, amountCurrency and destination currency and Table2 have the conversion rate(As mentioned in image conversation rate are in terms of USD). In another, known as Unicode UTF-8, it is translated as a sequence of two digits, 194 and 163. Table names must follow the rules for SQL Server identifiers, and be less than 128 characters. For example, in one commonly-used character encoding system, known as the ISO 8859-1, the pound is encoded as the number 163. SQL naming conventions for tables, and all the associated objects such as indexes, constraints, keys and triggers, are important for teamwork. Use the ROUND function to round the numbers to a specified number of decimals, so that the numbers fit within the column. And the pound symbol ('£') is one of those that has a different value depending on which encoding you use. Right-click on the affected column and select Clear Manual Sizing. Doing so allows the workbook to scale to larger resolutions while maintaining an appropriate design layout in lower resolutions. Resize the columns by placing the cursor over the border until a resize cursor appears, and then drag the columns until the expected data displays.ĭesign the dashboard for the smallest anticipated resolution and then set the resolution to automatic after the worksheet has been built. ![]() IssueWhen opening a dashboard in Tableau Reader or in Tableau Desktop, some data might appear to be replaced with "#" symbols.
