Hola: al crear una tabla de resumen a continuación, ¿alguien sabe cómo codificar en JSL para permitir que el script continúe ejecutándose si alguna de las columnas a continuación no existe?
dt3 << Resumen (Suma (: Fallo,: No evaluado,: Débil));
¡Gracias!
Necesita hacer un poco de seguridad de código en la lista de columnas para resumir.
Aquí está mi ejemplo:
dt3 = Current Data Table();
columns to summarize = {"fail", "not assessed", "weak"}; //columns you're interestd in, may or may not exist within table
column names = dt3 << Get Column Names( "String" ); //we need to grab the table columns to utilize only available columns
columns as names = {}; //we need to wrap both column names and our columns of interest in
For( i = 1, i <= N Items( column names ), i++, // 'As Name( ... )' to avoid issues with capitalization and such
columns as names[i] = As Name( column names[i] ) // loop here
);
columns to summarize within table = {};
For( i = 1, i <= N Items( columns to summarize ), i++,
If( Contains( columns as names, As Name( columns to summarize[i] ) ), // check to see that name exists as column header
Insert Into( columns to summarize within table, columns to summarize[i] )
)
);
Eval( Eval Expr(
dt3 << Summary( Expr( Substitute( columns to summarize within table, {}, Expr( Sum ) ) ) ) //fancy substitution for the summary table
) )
