I'm getting the error message Error at line 1, conversion error from string "" which I don't really understand, since when I drop the COUNT()-function, the query executes nicely. Do anyone know what I'm doing wrong? Thanks! sql interbase share|improve this question edited Jan 15 '10 at 11:49 asked Jan 15 '10 at 10:22 conciliator 3,29332656 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote I don't see anything wrong with using COUNT() in this case. Although it shouldn't matter you might try dropping all the parentheses in your WHERE clause. You also might try using COUNT(*) instead of COUNT(A.ID) just to see if it gives you different results. In any case, based on your description of the intent of the query I don't think that the query is going to do what you intended. If the query is supposed to return rows where the field is neither NULL nor empty I believe your WHERE clause should be WHERE A.VARCHARFIELD1 IS NOT NULL AND A.VARCHARFIELD1 <> '' With the 'OR' in there as originally written I think you'll get back every row in the table where A.VARCHARFIELD1 is NOT NULL, as the "field NOT NULL" predicate will allow in all non-NULL values, and since the two predicates are joined by an OR the second predicate won't matter. I hope this helps. share|improve this answer answered Jan 15 '10 at 12:11 Bob Jarvis 24.5k43766 Bob: well, I actually tried COUNT(*), but to no avail. You're quite correct regarding the 'AND'/'OR' thoug
nr = 0; END ... In this example, string 'ch' will be converted to integer. If conversion fails, 'nr' would get value zero. Make sure you use a separate BEGIN..END block for this, as WHEN works for the entire block. With Firebird 2.5 and above you can use a http://stackoverflow.com/questions/2070789/interbase-conversion-error-from-string regular expression to check whether the string is a valid number before converting it. You even check if number has certain digits, etc. Full explanation of the syntax can be found in Firebird 2.5 release notes: http://www.firebirdsql.org/rlsnotesh/rlsnotes25.html#rnfb25-dml-regex Do you find this FAQ incorrect or http://www.firebirdfaq.org/faq139/ incomplete?

Conversion error from string "$$$###" The following queries result in the error - Overflow occurred during data type conversion. Conversion error from string "$$$###". when running this in EMS Manager Lite or inside a delphi/report builder application. Select tbl1.FIRSTNAME, tbl1.Image2, Sum(FieldA) as TotalFieldA from Table1 tbl1 inner join Table2 tbl2 on tbl1.REG = tbl2.REF Group By tbl1.FirstName, tbl1.IMAGE2 If the references to the IMAGE2 field conversion error from is removed in the select and the group by then the query is fine. So is there some sort of issue where an Image (BLOB field) cannot be selected in a SQL Statement with a summing function. The Standard Select * from Table1 shows the image field no problem.

Publicar una respuesta 8 mensajes • Página 1 de 1 conversion error from string en Firebird por sarriaga » 2014-02-20 17:52 @786 Hola, ¿qué tal?Estoy realizando algunas consultas SQL con un script hecho en Perl. Verán: obtengo unos registros los cuales requiero insertar en una tabla en Firebird, solo que al ejecutar el Procedure para el INSERT me marca este error:conversion error from string "20140220161918" at copyEtiq.plpor lo que llegué a la conclusión de que este formato no es legible para Firebird, es decir no puede insertar las fechas de esta manera.¿De que forma puedo convertir estas fechas a formatos permitidos por Firebird? Tomando en cuenta que el campo de la tabla destinado en Firebird es de tipo TIMESTAMP.Espero que puedan apoyarme ya que no he encontrado mucha información respecto a este punto.Saludos sarriaga Perlero Nuevo Mensajes: 69Registrado: 2013-10-21 08:42 @404 Arriba Publicidad Re: conversion error from string en Firebird por explorer » 2014-02-20 19:07 @838 El formato de las fechas que admite Firebird lo tienes en la propia página de Firebird: Firebird Date Literals.Viendo tu cadena, me parece que no concuerda con ninguna de las mostradas.

Lo que debes elegir es cuál de todos esos formatos que te pone el manual debes escoger.
