WordPress database error: [Got error -1 from storage engine]

Hello,

This is the first time I’ve experienced this problem. Does anyone know how it can be resolved?

I received this when attempting to generate variations:

WordPress database error: [Got error -1 from storage engine]
SELECT t.*, tt.* FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON tt.term_id = t.term_id INNER JOIN wp_term_relationships AS tr ON tr.term_taxonomy_id = tt.term_taxonomy_id WHERE tt.taxonomy IN (‘wpsc-variation’) AND tr.object_id IN (2158, 2159, 2155, 2156, 2157, 2152, 2153, 2154, 2150, 2151, 2147, 2148, 2149, 2144, 2145, 2146, 2143, 2140, 2141, 2142, 2139, 2138, 2137, 2136, 2133, 2134, 2135, 2131, 2132, 2129, 2130, 2127, 2128, 2126, 2124, 2125, 2122, 2123, 2120, 2121, 2116, 2117, 2118, 2119, 2114, 2115, 2108, 2109, 2110, 2111, 2112, 2113, 2103, 2104, 2105, 2106, 2107, 2097, 2098, 2099, 2100, 2101, 2102, 2090, 2091, 2092, 2093, 2094, 2095, 2096, 2084, 2085, 2086, 2087, 2088, 2089, 2080, 2081, 2082, 2083, 2076, 2077, 2078, 2079, 2070, 2071, 2072, 2073, 2074, 2075, 2064, 2065, 2066, 2067, 2068, 2069) ORDER BY t.name ASC
