Data Type Mismatch (char Pada Foxpro
When creating table, we have to select the data type for each filed. Here is the list of data types in FoxPro 2.6.Data TypeDescriptionCharacter. To store string data type i.e., names, words.
Feb 28, 2002 RE: Data type mismatch!!!??? DEDMOD (Programmer) 27 Feb 02 22:51 I'd be happy to look at your form if you want to try to send to me at dedmod@msn.com, but it'd be helpful the have copies of the tables with sample data too, since otherwise it'd take a lot of effort to get it to the testing stage. Replace Command - Wiki for Microsoft Visual FoxPro development, software. REPLACE is one line. And a data type mismatch on a single line REPLACE with.
Can hold up to 254 characters. A-Z, a-z, 0-9, underscore & special symbols. Default length: 10Numeric. To store numerical value with decimal places. 0-9,. Can hold up to 20 digits.
Decimal part can be 0 to 18 digits. E.g. Usage: Marks, Roll NumberFloat.
It has signed numbers. Can hold up to 20 digits. E.g. Usage: percentage, averageDate.
Used to store date value. Default format dd/mm/yyLogical. Used to store Boolean value: True or False. Y, NMemo.
Used to store any amount of Text. The data stored in in a separate file with.fpt extension.General. Used to store text data, picture et.c,.
Used in FoxPro for Windows.
Hi all!In the command window the following works fineSELECT tblTargetTableyyy = 'divergcrtd' && the field divergcrtd is Lxxx =.F.REPLACE &yyy WITH xxx && works fineBut in code the following creates a Data type mismatch errorlcToField = RIGHT(ALLTRIM(crFldResult.FieldNames),;LEN(ALLTRIM(crFldResult.FieldNames)) - lnI - 4) && returns 'divergcrtd' tolcToFieldlcUsrDefVal = RIGHT(lcFirstTry,LEN(lcFirstTry) - 1) && Returns.F. TolcUsrDefValSELECT tblTargetTablefff = TYPE(lcUsrDefVal) && returns L to fff (just for check in debug)Replace &lcToField WITH lcUsrDefVal && generates Data type mismatch errorI cant see the difference between the command window code and theruntimecode.Whats wrong?RegardsChristinaFri, 01 Oct 2004 06:19:27 GMT.

To lcUsrDefVal Right is a string function, not a logical one. When you say it 'returns'.f. Ok, there seems to be some confusion between the string values '.t.' (note the use of quotation marks and the logical values,.t. (noquotation marks), plus, to add to the confusion, the type functionevaluates only strings that contain variable names or string literals. Firstof all, let's observe that if we evaluate the string '.F.' With the typefunction, it will return the character L, because the string contains thename of the logical value.f., but if we evaluate the string '.f.'
, typewill return the character C, because the string (enclosed in ), containsanother string: quote-dot-f-dot-quote. Also note that when we make anassignment of a string value to a memory variable, the quotation marks arenot included in the memvar, they merely serve to inform the fox of what typeof data we're storing. Finally, type(.f.) will return an error.In your command line version, xxx contains a logical value, but in yourcode, lcUsrDefVal contains a string.
Replace &lcToField WITH &lcUsrDefValshould work.As an aside, I'd recommend reading up on name expressions in the on linehelp. Use them wherever possible instead of macro substitutions.
Your codewill execute faster, and be more readable and debugable.-Lew SchwartzVisual FoxPro SolutionsDatabase Programming and Designwww.clsystems.com718-336-8225. Thanks for your interest Lew! Yes Right is a string function and returns the string contained in lcFirstTry execpt the its first character. If lcFirstTry = 'R.F.' lcUsrDefVal brings to contain '.F.'
I have been investigating the problem further and a the thing I dont understand is why lcUsrDefVal randomly seems to contain '.F.' And randomly.F. Even if lcFirstTry allways contain '.F.'

But as said before I dontunderstand why lcUsrDefVal randomly seems to contain '.F.' (C) andrandomly.F. (L) even if lcFirstTry allways contain '.F.' (C) when idebug hovering the pointer over the variable lcUsrDefVal.OK I can live withtaht.But I need to learn if there is more than one way (writing something to thevariable) to determine the type (C or L or M.) of a variable.Imagine a variable lcX (type C) containing '.T.'
How can I write its contents to another variable lcY so the variable lcYcontains.T. (type L)Or if lcX = '2002-04-16 12:32:10' (type C) and I want lcY = 20:32:10 (type T) an so on with other types.RegardsChristina. Ok, there seems to be some confusion between the string values '.t.'

The Integer and Currency data types only apply to fields. The INT and ROUND functions used above just give the appearance of the correctdata type. David Dunetz SweetWARE Hi David!
