Execute SQL command in Macro present in the form button

Hello, I’m trying to add an SQL command that sends the records from a table (All Diagnostics) that have the check box “True” and the Date, to another table (Patient Diagnostics). However, when debugging the code, the message appears: “Basic execution error. The argument is not optional” (line two).
The code I am using is as follows:

Sub do_sql(sql as string)

sql = 	"INSERT INTO ""3003. Diagnosticos de Enfermagem do Paciente""(""ID_DE"", ""Data"") SELECT ""ID_DE"",""Data"" 	FROM ""3003. Diagnosticos de enfermagem"", ""Datas do Diagnostico""	WHERE  ""3003. Diagnosticos de enfermagem"".""Selecionar"" = TRUE"

oresult = ThisDataBaseDocument.DataSource.getconnection("","").createstatement.executequery(sql)

End Sub

Hello,

The problem is this line:

Sub do_sql(sql as string)

It is stating to receive a string parameter - sql

Change it to:

Sub do_sql

Worked, thank you. Ratslinger
