         select 'EXEC DBMS_STATS.gather_table_stats('''||OWNER ||''', '''||TABLE_NAME||''', estimate_percent => 30);' from all_tables where owner = 'ESQUEMA1'

EJEMPLO DEL CODIGO DE SALIDA:
           EXEC DBMS_STATS.gather_table_stats('ESQUEMA1', 'TABLA1', estimate_percent => 30);
           EXEC DBMS_STATS.gather_table_stats('ESQUEMA1', 'TABLA2', estimate_percent => 30);

-----------------------------------------------------------------------------
UN CASO ENGORROSO:

EXEC DBMS_STATS.gather_table_stats('ESQUEMA1', '"ESQUEMA2.TABLA_UNO-3"', estimate_percent => 30);

EL MENOS PARECE HACER RUIDO.

PERO IGUAL PARECE MEZCLADO CON OTRO ESQUEMA, Y PERTENECER A UN ESQUEMA INICIAL.

SIN EMBARGO, ASÍ SE RESOLVIÓ, COMILLAS DOBLES.
