However, since Text retains the formatted appearance of cell values, Text may be useful, especially for populating userform controls with properly formatted text values. The recursive query joins each row of common table expression cte to the previous row of table t. However, Value2 is the quickest property to access range values and when reading it returns the true underlying cell value.
How do I programmatically set the value of a select box element using JavaScript?
I’m sure I could create a function to strip off the extra text but if something changes (i.e. reg key name) it might affect this. If you are processing the cell’s value then reading the raw .Value2 is marginally faster than .Value or .Text. If you are locating errors then .Text will return something like #N/A as text and can be compared to a string while .Value and .Value2 will choke comparing their returned value to a string. If you have some custom cell formatting applied to your data then .Text may be the better choice when building a report. LAG() refers to data from previous row and LEAD() refers to data after current row. Imagining that the «previous» variable reference the latest selected row.
(Excel) Conditional Formatting based on Adjacent Cell Value
It ignores Number Formats, Dates, Times, and Currency and returns numbers as the VBA Double data type, always. Since Value2 attempts to do less work, it executes slightly more quickly than does Value. Similarly, Value value stock to buy now checks for cell currency formatting and thenreturns values of the VBA Currency data type.
Only adding this as Google brought me here for a relevant reason and I eventually came up with the above one-liner for dredging the registry. Oracle, PostgreSQL, SQL Server and many more RDBMS engines have analytic functions called LAG and LEAD that do this very thing. If you need to break ties, you can add as many columns as necessary to the ORDER BY. Find centralized, trusted content and collaborate around the technologies you use most.

Access the «previous row» value in a SELECT statement

So if no property is specified for the range, the Value property is silently referenced by default. Value2 is almost always the best choice to read from or write to an Excel cell or a range… You could analyze the following tables for better understanding of differences between these three properties.

- Text will return ####### when columns are too thin and it will slow down even more when some row heights are adjusted.
- It ignores Number Formats, Dates, Times, and Currency and returns numbers as the VBA Double data type, always.
- Similarly, Value checks for cell currency formatting and thenreturns values of the VBA Currency data type.
- So even though you asked for the item by name, to get its value you have to use the name once more.
- If your VBA code will be working with the Date data type, it may make sense to retrieve them with the Value property.
Basically, it makes every registry value a PSCustomObject object with PsPath, PsParentPath, PsChildname, PSDrive and PSProvider properties and then a property for its actual value. So even though you asked for the item by name, to get its value you have to use the name once more. And check the type of the variant using VBA.VarType(v) before you attempt an explicit coercion.
Of course with a select like that I will end up with n-1 rows selected in a table with n rows, that’s not a probably, actually is exactly what I need. If arr is a variable of type Variant, the above line actually creates an OLE SAFEARRAY structure of variants 26 columns wide and 999 rows tall and points the Variant arr at the SAFEARRAY structure in memory. First we get an object containing the property we need with Get-ItemProperty and then we get the value of for the property we need from that object. The example above gives you the PS version for «legacy»/compatibility-mdoe powershell (1.0 or 2.0). And so on.So this is an easy way of passing the value to another page (with select option list) through GET in url.

And strangely, that precision is cut to just two decimalplaces when using Value to write a VBA Currency variable to a worksheet range. The Value property, on the other hand, checks if a cell value has a Number Format of Date or Time and will return a value of the VBA Date data type in these cases. If your VBA code will be working with the Date data type, it may make sense to retrieve them with the Value property. And writing a VBA Date data type to a cell will automatically format the cell with the corresponding date or time number format.
However, Formula and FormulaR1C1 must be used to read cellformulas. The read-only Text property always returns a VBA String data type. The value returned by Range.Text is a textual representation of what is displayed in each cell, inclusive of Number Formats, Dates, Times, Currency, and Error text. This is not an efficient way to get numerical values into VBA as implicit or explicit coercion is required. Text will return ####### when columns are too thin and it will slow down even more when some row heights are adjusted.
After about 12 trials of similar processes, I could not see any significant differences in speed so I would always recommend using Value. So you can retrieve and store the value of a cell in either dynamic, var or object but note that the value will always have some sort of innate type that you will have to act upon. Connect and share knowledge within a single location that is structured and easy to search. Newer versions of Sql Server also have the LAG and LEAD Windowing functions that can be used for this, too. I need to calculate the difference of a column between two lines of a table.
Andwriting a VBA Currency data type to a cell will automatically apply the currency Number Format to the appropriate cells. Can anyone help me pull the value of a registry key and place it into a variable in PowerShell? So far I have used Get-ItemProperty and reg query and although both will pull the value, both also add extra text. I need just the string text from the registry key and ONLY the string text from the key.
Similarly, both Formula and FormulaR1C1 always return values as a VBA String data type. If the cell contains a formula then Formula returns its A1-style representation and FormulaR1C1 returns its R1C1 representation. If a cell has a hard value instead of a formula then both Formula and FormulaR1C1 ignore all formatting and return the true underlying cell value exactly like Value2 does… Again, this is not an efficient way to get numerical values into VBA as implicit or explicit coercion is required.
The selected answer will only work if there are no gaps in the sequence. However if you are using an autogenerated id, there are likely to be gaps in the sequence due to inserts that were rolled back. LEFT JOIN the table to itself, with the join condition worked out so the row matched in the joined version of the table is one row previous, for your particular definition of «previous». Out of curiosity, I wanted to see how Value performed against Value2.
