Matthew,
The error message regards the expression, not the string values, nor=20
the 'number of where' or tables involved. The MapBasic compiler is not
very powerfull...
Try to use :
lc_select =3D "Select bl.BUS_LOC_CD "
+ "From Business_Locations bl, "
+ "Orders o,"
+ "Order_Element_Schedules oes, "
+ "Trips tr, "
+ "Tasks t, " =20
lc_select =3D lc_select + "Scheduling_Scopes ss, "
+ "TSD tsd"
+ "Where bl.FAC_ID =3D o.FAC_ID_FK " ' -- joins Business_Locations to =
Orders
+ "And t.SCHG_ATY_ID =3D oes.SCHG_ATY_ID_FK " ' -- joins Tasks to =
Order_Element_Schedules
+ "And o.ODR_ELE_ID =3D oes.ODR_ELE_ID_FK " ' -- joins Orders to =
Order_Element_Schedules
+ "And tr.SCHG_ATY_ID =3D t.SCHG_ATY_ID_FK " ' -- joins Trips to Tasks
lc_select =3D lc_select + "And tsd.SCHG_ATY_ID =3D tr.TSD_SCHG_ATY_ID_FK =
" ' -- joins TSD to Tasks
+ "And oes.ODR_ELE_SCHG_REL =3D 13 "
+ "And ODR_SCHG_STS =3D 'M' " ' -- identifies all Mandatory orders
+ "And ss.SCHG_SCP_ID =3D " + gf_scopeid + " " ' -- identifies orders =
for current scope only
+ "And (tsd.SHFT_DT < ss.SCHG_SCP_PD_ST_DT " ' -- EITHER tsd date is =
before the current shift date
+ "Or (tsd.SHFT_DT =3D ss.SCHG_SCP_SCH_PD_ST_DT " ' -- OR tsd date is =
equal to the current shift date
+ "And tsd.SHFT_AMPM < ss.SCHG_SCP_SCH_PD_ST_SHFT))" ' -- AND tsd =
time is before current shift time
Hope this help.
Carlos

Subject: MI-L "Expression too Complex" error message
I'm getting the above message, when I attempt to use the =
Server_Execute function, in conjunction with the following string.
lc_select =3D "Select bl.BUS_LOC_CD "
+ "From Business_Locations bl, "
+ "Orders o,"
+ "Order_Element_Schedules oes, "
+ "Trips tr, "
+ "Tasks t, " =20
+ "Scheduling_Scopes ss, "
+ "TSD tsd"
+ "Where bl.FAC_ID =3D o.FAC_ID_FK " ' -- joins Business_Locations =
to Orders
+ "And t.SCHG_ATY_ID =3D oes.SCHG_ATY_ID_FK " ' -- joins Tasks to =
Order_Element_Schedules
+ "And o.ODR_ELE_ID =3D oes.ODR_ELE_ID_FK " ' -- joins Orders to =
Order_Element_Schedules
+ "And tr.SCHG_ATY_ID =3D t.SCHG_ATY_ID_FK " ' -- joins Trips to =
Tasks
+ "And tsd.SCHG_ATY_ID =3D tr.TSD_SCHG_ATY_ID_FK " ' -- joins TSD to =
Tasks
+ "And oes.ODR_ELE_SCHG_REL =3D 13 "
+ "And ODR_SCHG_STS =3D 'M' " ' -- identifies all Mandatory orders
+ "And ss.SCHG_SCP_ID =3D " + gf_scopeid + " " ' -- identifies =
orders for current scope only
+ "And (tsd.SHFT_DT < ss.SCHG_SCP_PD_ST_DT " ' -- EITHER tsd date is =
before the current shift date
+ "Or (tsd.SHFT_DT =3D ss.SCHG_SCP_SCH_PD_ST_DT " ' -- OR tsd date =
is equal to the current shift date
+ "And tsd.SHFT_AMPM < ss.SCHG_SCP_SCH_PD_ST_SHFT))" ' -- AND tsd =
time is before current shift time
I can pretty much guess what it means, but does anyone know exactly =
what the limits are?=20
Are they on number of characters in the string, number of tables =
involved, number of 'where' clauses, etc?
Thanks in advance.
